There will be a full closure of Interstate 55 from Carondelet to 4500 Broadway starting at 9 p.m. on Friday, March 18 and reopening by 5 a.m. on Monday, March 21 to allow the contractor to safely remove the bridge. Motorists can use the following detour while this section of Interstate 55 is closed:
This construction is part of the Interstate 55 Bridge Replacement Project to remove and replace the Holly Hills and Delor Bridges. Both of them were built in the early 1960s and have deteriorated beyond the point of simply repairing the bridges. Dates are still being finalized for when the Holly Hills Bridge will be removed and replaced.
The Holly Hills and Delor Bridges will be built in the same location with a higher clearance over the interstate to meet current Federal Highway standards. MoDOT will also upgrade the sidewalks and pedestrian ramps to American Disabilities Act (ADA) standards. Replacing both the Holly Hills and Delor Bridges costs a total of $3 million dollars. The entire Interstate 55 Bridge Replacement Project is expected to be complete by the end of 2011.
