MoDOT spokeswoman Linda Wilson issued a statement this afternoon reporting that the Poplar Street Bridge is structurally sound. See her comments at the end of this post.
Missouri Department of Transportation crews will examine the Poplar Street bridge today
after a large chunk of concrete fell off the structure Sunday. View Larger Map
The debris dropped from an exit ramp from the bridge and caused highway officials to shut down part of Interstate 70 for about an hour. It was hardly the first time the 43-year-old bridge has caused alarm.
The bridge has been in a "constant state of disrepair"
since at least 2003 and carries nearly 125,000 vehicles a day as St. Louis' main bridge spanning the Mississippi River.
So, anyway, when's that new bridge going to be finished
MoDOT response from Linda Wilson:
MoDOT's Bridge Inspection crews have briefly inspected the bridge ramp
from the Poplar Street Bridge to westbound I-55 and have confirmed the
concrete that fell off yesterday was just off the outer surface of the edge
of the bridge. There is nothing structurally wrong with the ramp
The crews are doing a proactive review of all of the bridges in
the downtown area to look for other similar cracks and knock off any
other potentially loose concrete. The crews currently have the right lane
closed on eastbound I-70 in the depressed section. They will inspect the
bridges over the depressed section and work their way under the Poplar
Street Bridge complex and down part of I-55 inspecting all the overhead
bridges as they go.
With the recent freeze and thaw temperatures we
have had, the facade along edge can get cracks in the older bridges. The
crews are looking to remove anything from the edge that might break loose. Motorists should expect lane closures on eastbound I-70 to southbound I-55
and northbound I-55 to westbound I-70 for several more hours.
