Snowplows and emergency response vehicles equipped with new driver-assisted technologies to provide safer operation during extreme low-visibility winter driving conditions began operating Nov. 7 along the Hwy 7 corridor between the Twin Cities and Hutchinson.

The vehicles—three Mn/DOT snowplows, one McLeod County snowplow, one Hutchinson Area Ambulance and one Minnesota State Patrol squad car—are part of a field test scheduled through March 2002. Data will be collected from the "smart" vehicles as drivers perform their normal duties.

Driver-assisted technologies include magnetic roadway tape, differential global positioning system, on-board radar and heads-up displays, and other specialized warning systems for vehicle guidance and crash avoidance. These technologies allow snowplow, ambulance and patrol car drivers to see a virtual image of the roadway under adverse conditions, warning them of approaching obstacles.

"This innovative technology is recognized worldwide as setting a new pace in the intelligent transportation systems industry," Commissioner Elwyn Tinklenberg told the audience in Hutchinson at the Nov. 7 kickoff for the program. "We’re pleased to have Minnesotans be the first to benefit from it."

Also present at the kickoff were Mn/DOT’s John Scharffbillig, field project manager, and Craig Shankwitz, technical liaison, from the University of Minnesota.

Other project partners are the Department of Public Safety, McLeod County, City of Hutchinson, Hutchinson Ambulance, 3M, International Truck, Altra Technologies, and North Central Ambulance and Emergency Automotive Technologies, Inc.

 Bike unit rolls through 25 years of hot, cold economic times

25th anniversary logo

Editor’s note: This is one in a series of articles looking back on the department’s first 25 years—remembering the people, issues and cultural forces that have shaped the agency and the milestones Mn/DOT has achieved.

The oil shortage of the 1970s made mostly temporary changes in Americans’ lifestyle choices, economists claim. Minnesotans, however, have at least one long-lasting change from that era that’s embedded in the soil itself: a comprehensive statewide bikeway system begun in that decade.

Bicycle transportation was part of Mn/DOT’s charge from the very beginning. State legislation in 1976 and 1977 authorized planning for and construction of bikeways, along with developing bike maps to help residents find and use bikeways effectively.

This same legislation also brought Nancy (Mahle) Melvin from the Department of Natural Resources to lead Mn/DOT ’s new bicycle transportation unit from 1977 to 1985.

Creating the bikeway system

"When I came to Mn/DOT," Melvin said, "I had a photocopy of the legislation, a phone book, and a phone, and I was told to set up a ‘bike program.’ So I began knocking on doors, making calls and learning this complex organization."

The Legislature had directed Mn/DOT to do what staff referred to as "the three C’s: coordinating, constructing and communicating information statewide on bicycle transportation."

"The bicycle transportation construction program was aggressive," Melvin said. "We had our hands full. We were obligated by state law to do needs analysis, mapping and construction of bicycle trails and road improvements. We needed to develop a process to integrate non-motorized transportation into our planning and development work."

Laying a solid foundation

The key to the success of this program, she said, was cost-sharing and local involvement.

"We had frequent contacts with districts, cities and counties to manage a grants-in-aid matching program," Melvin said. "This enabled cost-sharing of construction projects and stretched the funds to accomplish the priority needs. Two examples are the bike-pedestrian accommodation on the Cedar Avenue Bridge at the Minnesota River and the I-494 Bridge from Bloomington to Eagan."

These days, Melvin works as transportation planning director for Metro Division’s Office of Planning and Investment Management. It’s been 16 years since she last served as chief of the bicycle unit, but Melvin can still quickly reel off a list of her section’s accomplishments.

"We constructed 1,200 miles of bikeways and road enhancements costing $12 million," she said. "We mapped the entire state. We developed formulas to evaluate roads for bicycle use and suitability. We developed a standards manual for designing bikeway facilities. We printed detailed bikeway maps. We had a speaker’s bureau, promoted safety, and talked with bicyclists, city planners and engineers to learn about gaps and opportunities."

Bikeway planning today: different driving forces

It’s been many years since we’ve had a long-term oil shortage, but two prominent issues today could revive public interest in bikeways, according to Bob Works, director of the Sustainable Transportation Initiatives section, Office of Environmental Services. STI promotes walking, telecommuting and bicycling.

Works participates every year in the Bike, Bus or Pool (B-BOP) spring event and believes that "the national obsession with fitness can be a driver for bicycling." He also cited mental and emotional benefits "from biking or walking to work. When I bike to work, I have a whole different outlook on my day."

The other issue—traffic congestion—has become the public’s biggest transportation concern today. Works sees interest growing in bicycling’s potential to help reduce traffic.

"From the federal level, there’s substantial support from the Federal Highway Administration to increase the percentage of people using modes other than cars for commuting," Works said. "We need to work with local governments to help people see how to create bicycle network systems in their communities. Too often they have mainly a bike trail or two, but not a system."

Bicyclists on bike trail

These 1985 bicyclists enjoy the most popular of the three types of bike enhancements: separate bicycle paths that occasionally intersect with roads.

Surveys suggest public interest

Recent surveys suggest that public interest in bicycling as an alternative means of transportation may be rising. Respondents to the 2000 FHWA nationwide survey placed biking high on their list of perceived alternatives to driving.

"We’re paying a lot of attention to what our customers say via market research surveys," Works said. "There’s an untapped market out there of people who’d bike to a bus facility that has a secure place to store bikes."

According to the FHWA’s survey, respondents indicated the following:

  • 70 percent said that expanding existing public transportation would better serve their communities.

  • 69 percent suggested building new bikeways and sidewalks.

  • 68 percent wanted better quality traffic information.

  • 64 percent advocated expanding existing highways.

A second study, the University of Minnesota’s 1999 Statewide Tracking Study, yielded these findings:

  • 18 percent of working Minnesotans said they live close enough to their workplace that they would consider bicycling to work.

  • 4 percent already bicycle to work at least a few days a year.

  • About 25 percent of the population bicycles to other destinations as an alternative to driving.

  • An additional one-third said they would consider doing so.

Bicyclists on shoulder of road

An alternative bike enhancement-paved six-foot-plus shoulders-accommodates these 1985 bicyclists. The bicyclist on the highway is there legally; bicycles are a legal road vehicle unless otherwise prohibited.

Biking directions

"A lot of good things have been built and advocated in the last 25 years, and we want to continue in that vein," said Darryl Anderson, state bicycle coordinator. "We really want to build upon the past as we strike out into the future."

Today’s limited funding, however, requires a more targeted approach, Anderson said.

"We want to maximize our limited resources and provide the right tools in the right places to provide the best possible guidance for designers," he said.

Recent efforts and current plans include:

  • Publishing the 2001 Twin Cities Metro area system plan;

  • Updating Mn/DOT’s design standards manual and statewide system plan;

  • Sponsoring bike facilities design training sessions around the state;

  • Printing new bike maps;

  • Working with Mn/DOT planners in district offices and Central Office to design highways that bicyclists can use safely; and

  • Looking at how bikeways, pedestrian facilities and telecommuting fit into Mn/DOT’s 2003 transportation plan (in draft stage).

A Jan. 1999 technical memorandum clearly spells out Mn/DOT’s current direction on bicycles:

"When developing a trunk highway improvement project, Mn/DOT will determine what is necessary to safely accommodate bicycles in that section of roadway."

-Technical Memorandum #99-04-#S-01, 1/19/99

Bike trail under overpass

Minnesota has the first "bicycle freeway" in the nation: the Cedar-Lake Bicycle Path, which extends about four miles from Hwy 100 to downtown Minneapolis, paralleling I-394.

Planning new trails

Anderson and Works said they have seen "a real willingness by planners to work with bicycle checklists and design plans." This is evident in transportation plans coming from the office of Mn/DOT’s former bicycle unit chief.

Melvin, who today works with Metro Division’s portion of the transportation system plan and "Moving Minnesota" (advantages for transit, bottleneck removal, integrated regional corridor development), said she still watches out for bikeway opportunities in her section’s transportation planning.

"Bicycle transportation is an important element of modal planning," she explained. "We incorporate bikeways in our planning products when we plan for highway construction. We need to keep a systems perspective and work together to make the network operate better. Having bikeways as one component of our planning makes good business sense."

Anderson believes that the timing is right for shifting bicycle transportation into high gear.

"We really have an opportunity with this administration," he said. "They’re very interested in a multimodal and holistic approach to transportation. We want to really ‘step up to the plate’ as best we can to provide realistic pedestrian, bicycle and telework options."

Commissioner Elwyn Tinklenberg added, "This administration’s commitment to multimodal transportation means providing transportation choices for Minnesota. Bicycling is an important part of that—not an afterthought, not a sideline activity, but a full partner."

Mn/DOT marks its 25th anniversary on Nov. 8

On Thursday, Nov. 8, Mn/DOT marks the 25th anniversary of the day the department was officially designated by the Legislature. The agency was formed on Nov. 8, 1976, to encompass all major transportation modes in one department.

Related legislation authorized Mn/DOT to create a bikeway system and develop maps showing suitable biking routes (see above article).

 Salt supplies adequate for upcoming winter season

Shed full of salt

A salt shortage anticipated this winter in the United States is not expected to affect Mn/DOT, according to Robert Vasek, Mn/DOT’s maintenance operations support engineer.

Currently, the department has 292,000 tons of salt under contract—enough to meet the anticipated demand for the season, he said. During an average winter, the state uses approximately 200,000 tons of salt.

This year’s nationwide salt shortage is linked to last year’s tough winter, Vasek said. In addition, spring flooding delayed barge shipments and prevented vendors from stockpiling larger quantities of salt locally. Some states and local governments may suffer shortages this winter because of a delay in purchasing salt supplies for the upcoming winter.

Most rock salt mining takes place in Michigan, Kansas and Louisiana. The average price is $30-50 per ton. Prices are running about 15 to 20 percent higher than last year. Mn/DOT purchases salt from eight vendors, Vasek said. Some salt is delivered from summer to fall, before the snow and ice season. More salt is delivered throughout the winter season as needed. Mn/DOT’s storage capacity is approximately 50 percent of its annual needs.

"We’re confident our vendors can satisfy their contract obligations, but we are following up to be sure," Vasek said.

In the event of shortages, other chemicals are also available for snow and ice removal including magnesium chloride and calcium chloride. Mn/DOT has experimented with other ice removal chemicals for use around the state.

This sample light rail transit car 'stops' next to a park bench in this indoor full-scale mockup of an LRT line.

Light rail construction continues on time and on budget as the first construction season comes to a close. Recent developments include:

Utilities relocation

The Eighth U.S. Circuit Court of Appeals Nov. 1 upheld U.S. District Judge John Tunheim’s order to have Xcel Energy complete relocation of its underground utilities by February 2002. The ruling also requires Mn/DOT to post an $8 million bond to ensure monies are available in case the department is forced to pay relocation costs. Mn/DOT and Xcel Energy dispute who should pay the costs for utility relocation. Click here to view the May 30, 2001 and the March 14, 2001 Mn/DOT Newsline articles about the lawsuit.

Construction

  • Crews are welding rail in preparation for laying the first sets this November within the Metro Transit Operations and Maintenance Facility Yard at I-94 and Cedar Ave in Minneapolis.

  • Private utility companies diligently work to relocate utilities on south Fifth Street in downtown Minneapolis by a February 2002 deadline.

  • Progress also can be seen south of downtown at the 28th Street Bridge, along the west side of Hiawatha from 32nd Street south to Minnehaha Avenue, and at the airport tunnel near Fort Snelling and the Humphrey Terminal.

  • Crews will perform limited construction activities throughout the winter months at the Maintenance & Operations Facility (Yard and Shops) and tunnel boring site.

The Preservation Alliance of Minnesota recently recognized Mn/DOT for its inventory of historic roadside structures. The award was one of several that the alliance presented Nov. 3 to honor the people and organizations that support its mission to preserve and promote Minnesota’s historic resources.

Commissioner Elwyn Tinklenberg accepted the award at the ceremony held in Duluth.

Mn/DOT earned its award for an inventory of 102 historic wayside structures built on the trunk highway system before 1961. The Office of Technical Support contracted with a consultant to conduct the inventory. In addition to listing structures, the inventory promotes appreciation and understanding of the historical forces that led to their construction and help determine their importance.

The structures include shelters, overlooks, retaining walls, dams, rock gardens, council rings and bathhouses. Many used native stone such as granite and limestone in their construction.

The oldest structure is Camp Release State Memorial Wayside built in 1894 near Montevideo, but the majority of the properties were built in the 1930s and 1940s as part of federal relief programs created by President Franklin Roosevelt’s New Deal.

Nov. 3: temperatures were in the mid-60s, football fans were in short sleeves, the hot dogs were slathered in mustard. Who would think that winter was just around the corner?

John Hanzalik, Maple Grove’s highway maintenance supervisor, for one, did. That’s why he and other Mn/DOT staff took the opportunity to distribute winter driving information at the Gopher Snowplow Safety Day at the Metrodome. Fans even got to see a snowplow truck, which was parked outside the dome, up close.

Watch for these upcoming winter work zone safety events:

  • Nov. 5-9: Winter Hazard Awareness Week

  • Nov. 13: Snow and ice media expo at the Cedar Avenue truck station in Minneapolis

For more information about work zone safety, contact Mary Meinert, 651/297-5868.
