This week, the Minnesota Department of Transportation will put the finishing touches on the new Cedar Lake Regional Trail bridge carrying pedestrians and bicyclists over Hwy. 100 in St. Louis Park.
Then the agency will start razing the Hwy. 7 bridge as part of the $60 million project to upgrade Hwy. 100 to three lanes in each direction between I-394 and 36th Street. Part of the work was done last year with a new bridge and interchange put in at Minnetonka Blvd. The rest of the work, including extra lanes and a new overpass and interchange at Hwy. 7, will be completed this construction season.
That news has some motorists wondering why the Hwy. 7 bridge over Hwy. 100 was shut down last fall when demolition was not planned until this spring.
"Highway 7 over Highway 100 was closed all winter when there was no work done on the bridge," one Drive reader commented. "I have heard it was closed completely because there was no pedestrian and bike crossing due to the Cedar Lake Trail bridge replacement. Did MnDOT really give priority to a couple pedestrians and bikes over the 30,000 vehicles that use Highway 7 each day?"
No, says MnDOT spokeswoman Bobbie Dahlke.
"Although a lot of people use that trail — it's not just a few — that was not the reason we didn't demo it or let people on it," she said.
Here's why: MnDOT closed the structurally deficient Hwy. 7 bridge in October when the new Minnetonka Blvd. overpass opened. The soil surrounding the Hwy. 7 bridge was bad and not conducive for building a new bridge. Crews dug out the old soil and replaced it with good soil and sand, which is heavier and necessary to support the foundation for the new bridge, Dahlke said.
"We had to let that sit for three to four months. And while we did that, it was not safe to put the weight of vehicles on the bridge," she said.
