An event as traumatic as the Interstate 35W bridge collapse created shock waves throughout the department. Within a few moments, Mn/DOT’s priorities shifted. Business-as-usual was no more. Roles, responsibilities and duties changed markedly for many employees.
From every quarter, employees contributed to the department’s response to the tragedy. In this issue of Newsline, we will tell some of their stories. We will tell more of those stories in future editions.
From “routine to rescue” in a split second

On the night of Aug.1, 2007, student worker Garrett Schreiner just finished his shift at the Regional Transportation Management Center in Roseville.
Typically, the RTMC staffs five people during peak periods, including a traffic broadcaster for KBEM radio, two dispatchers who monitor Twin Cities area traffic and two operators who monitor ramp metering and incidents. That night, Todd Fairbanks was keeping an eye on traffic on the east side of the Twin Cities metro area; Amber Tracy was working the west side monitors, and Mary Meinert was monitoring the ramp metering, detection and signage systems.
There was an incident on Interstate 394 involving a stalled bus. A trooper asked for a FIRST driver’s assistance in the area. Just a normal, quiet night.
Shortly after 6 p.m., everything changed.
Fairbanks heard a State Patrol dispatcher suddenly say something about a collapse. He tried to operate camera 629, then camera 630 (located just north of the 35W Bridge) but the screens were blank. Meinert then turned camera 628, located just south of the bridge, so it faced north toward the bridge.
“At first I thought we were looking at a side street where they’re doing construction. I thought, ‘Where are all the construction workers?’” Fairbanks said. “Then I started to recognize what we were looking at and my stomach just dropped.”
For a moment, there was an eerie quiet in the control room. Then, a State Patrol dispatcher started fire and ambulance crews, while the RTMC staff started shutting down roadways.
“A trooper called FIRST driver Julie Todora on the radio, and suddenly, the Nextel radios went crazy. FIRST drivers started calling in and asking where they were needed,” he said.
Fairbanks’ mission was to get FIRST drivers located on the east side of the Twin Cities to cut off traffic headed southbound on I-35W. RTMC staff wanted to keep drivers away from first responders and also away from the scene.
Fairbanks feels overwhelming sadness about that night, which seems like a blur. What stands out in his memory is how quickly the State Patrol, the Minneapolis Police and FIRST drivers went from “routine to rescue” mode in a split second. He was also impressed with how fast the Emergency Operations Center got up and running.
“They were mobilized and working within an hour of the bridge collapse,” he said.
Fairbanks ended up staying in the control room until 10 p.m. that night—three hours past the end of his shift. He said the feeling afterward was not unlike his reaction to the events of 9/11—sheer horror that such a massive structure could come tumbling down.

When Amber Tracy first saw camera 628 turn toward the collapsed bridge, her reaction was complete shock. She’d driven that route every day from Eden Prairie for the last couple of years. Tracy remembers thinking, “This is going to be huge news.” She also quickly realized that she was one of the first to see the aftermath of the collapse.
Immediately, she alerted the news media on the radio channel. The FIRST unit drivers, who monitor the State Patrol radio frequency, worked quickly with the State Patrol to shut down northbound I-35W at the I-94 commons, just south of downtown Minneapolis , as well as shutting down northbound Hiawatha, which leads into northbound 35W.
Shortly after the incident, people started coming into the control room—from RTMC supervisors and Incident Command staff to extra State Patrol dispatchers. Once the FIRST units were situated roads closed and signs up, Tracy stayed until about 8:45 p.m. Maintenance crews came on scene and relieved the FIRST drivers, normal protocol in emergency situations.
The day after the tragedy, Tracy went to Chicago on a previously-planned visit, and that helped clear her head. Since returning to work, everything has been fine in the control room. She notes the improved traffic flow patterns since the work was done on I-94 this past weekend.

Mary Meinert heard the State Patrol dispatcher yell across the room, “35W Bridge down.” Moving camera 628 so it faced north, she saw white concrete smoke rising above where the span had just been.
Meinert started putting up electronic message signs, 20 in all, and put “road closed” in the CARS system.
Within 30-35 minutes, there was an energetic buzz in the room while the three co-workers got everything in place as well as fed traffic updates to Don Zenanko, who was providing continuous coverage on KBEM.
During a crisis like that, your brain is going a million miles an hour, and it's hard to wrap your brain around the tragedy.

Meanwhile, they also had to stay on top of all the other incidents that were taking place around the system that night.
Meinert remembers the noise and energy levels rising in the room, as the radio went crazy.
“During a crisis like that, your brain is going a million miles an hour, and it’s hard to wrap your brain around the tragedy,” she said. “It was phenomenal the way Mn/DOT staff have stepped up to the plate.”
Following the end of her shift, she went upstairs to her office to cancel RTMC facility tours for the next day.
According to Meinert, there’s a real sense of teamwork and ownership among the RTMC staff.
“The general feeling is, ‘these are my roads, my drivers; this (the tragedy) doesn’t happen on my watch.’”
FIRST units take control of traffic
By Lisa Yang
Mn/DOT’s Freeway Incident Response Safety Team helps highway motorists with changing tires, providing gasoline for vehicles, assisting the State Patrol by removing debris, and providing traffic control and scene security at crashes.
When the I-35W Mississippi River Bridge collapsed, FIRST units on duty responded by providing initial traffic control on northbound and southbound I-35W, along with the State Patrol and local law enforcement immediately after the collapse.
Julia Todora was on duty and was one of the first FIRST units to respond. They began closing northbound and southbound lanes going towards the bridge and sent traffic to east I-94 to make sure that emergency staff could get through to the site.
“We didn’t have a view of what went on,” Todora said. “But, another unit came and had a computer in the truck, so we were able to get a visual of what was going on.”
FIRST was relieved of traffic control duty by Mn/DOT Maintenance at approximately 7:15 p.m. , per their normal operating procedures, according to Todd Kramascz, operations supervisor at the Regional Traffic Management Center.
“I was impressed with the response time from different agencies,” Todora said. “It was fast and the agencies worked well together.”
Quick response sets up safety command post at bridge site

Less than hour after the I-35W bridge fell, district officials established a safety command post a few blocks from the site.
Doug Thies, Metro District, was the first safety administrator to arrive at the collapse site. Thies heard a radio report about the collapse, checked with Metro Dispatch and then headed for the bridge.
He ordered all the Mn/DOT employees off the bridge and established a safety command post with the Minneapolis Fire Department and other agencies.
District 7’s Dale Plemmons later joined him. They worked via e-mail and phone with Julie Bottolfson, Metro’s safety services supervisor, who was then in Ohio.
They quickly put stringent standards in effect to ensure the safety of rescue workers, Mn/DOT staff, public officials and others who required site access.
Mn/DOT safety officials also mapped the site for potential hazards to emergency responders and others working on the collapsed bridge, Bottolfson said.
They have provided mandatory training, briefings and safety gear to anyone who is granted site access around the clock since the Aug. 1 bridge collapse.
Bottolfson said that Mn/DOT safety officials are working with the federal and state Offices of Safety and Health Administration, the National Transportation Safety Board, the FBI and local authorities to ensure safety measures are followed during the recovery operation.
Safety staff conduct two daily briefings on site conditions. They also require that all work crews complete a daily safety plan.
The Metro District representative on the Incident Command staff provides overall direction for the safety staff.
“We’re working cooperatively with these agencies, Mn/DOT employees and our contractors,” Bottolfson said. “This is a very fluid situation; we’re adopting procedures and standards as needed to make sure there are no more casualties connected with this incident.”
A big 10-4: Digital radio system links responders following bridge collapse
By Craig Wilkins
While envisioned for use in natural disasters or a terrorist attack, the state’s digital radio system that links emergency response agencies proved its mettle following the I-35W bridge collapse.
“The system worked as planned; it did what it’s supposed to do,” said Tim Lee, who was acting Electronics Communications director at the time of the incident.
Mn/DOT operates the system’s radio framework.
Known as ARMER/911, the 800 MHz system is fully operational in Anoka , Carver and Hennepin counties. Its key feature is interoperability which allows responders to talk with each other and with others in pre-selected talk groups.
The system provides state, county, city, fire, police and other agencies with a set of digitally linked radio channels they can share during crisis situations.
Extensive training in the system’s use by agency staff in the Twin Cities metro area was a key factor in its success, he said.
The system’s back-up capability also played a role. Lee said, ironically, that when a fiber-optic cable carried on the I-35W bridge was lost due to the collapse, the system immediately switched to another cable connection.
That connection links the Regional Transportation Management Center in Roseville with the Hennepin County Sheriff’s Office in Golden Valley.
Ramsey and Dakota counties will have the system working by the end of this year, Lee said. Scott and Washington counties will start using the system in 2008.
There were a few minor problems, Lee said, but the system’s ability to allow scores of agencies communicate effectively with and among each other functioned well as it has during major snowstorms and other previous events.
Emergency preparedness key to quick response in I-35W disaster
By Donna Lindberg
The collapse of the I-35W bridge put Minnesota ’s emergency preparedness procedures to the test, particularly in redirecting traffic when a route becomes blocked.
“Mn/DOT has been working with other state and local agencies to coordinate individual plans, to know who’s responsible for different areas of the system,” said Cathy Clark, Homeland Security and Emergency Management planner.
Clark was part of the group that developed a 2005 traffic management plan for five high-risk areas in the Twin Cities area that provides guidance for the quick evacuation of citizens and access of emergency response staff into a disaster site.
We’ve done exercises, responded to flooding and tornadoes, but this is our first
major event.
The response plan worked well.

“The plan is situation-dependent and doesn’t designate alternate routes in advance of potential closure of certain parts of the system,” Clark said. “It is a template approach that helps responders identify areas of high risk and who’s responsible for different functions in an emergency.”
According to Sonia Morphew Pitt, Mn/DOT’s Homeland Security and Emergency Management director, this plan involves more emergency management than planning.
“It’s different on the coasts where they know when and where hurricanes will hit and can post evacuation routes in advance,” Morphew Pitt said. “In the Midwest , we don’t get early warnings, and disasters can happen anywhere, so we can’t designate specific routes in advance. We need an all-hazards plan that allows us to respond immediately incident by incident.”
Morphew Pitt said that the I-35W bridge collapse was the first event of this magnitude in the Twin Cities metro area.
“We’ve done exercises, responded to flooding and tornadoes, but this is our first major event. The response plan worked well. We deferred to a command structure and everyone knew their assignment and how to respond,” she said.
Federal Emergency Management Agency training that Mn/DOT employees took contributed to the coordinated response to the disaster.
“Everyone reacted well,” Morphew Pitt said. “Homeland Security Presidential Directive #5 required that all Mn/DOT employees receive incident management system training. That training, which was completed in June 2007, turned out to be very valuable in this situation.”
Communications was also an important part of the Twin Cities metro area evacuation plan.
“What the Metro evacuation traffic management plan does is help educate the public before emergencies happen about where they should go to get evacuation or detour routes,” said Morphew Pitt.
