Update: Northbound I-55 entrance ramp from Union Road to close Monday

The Missouri Department of Transportation and its contractor Fred Weber, Inc., will close the northbound Interstate 55 entrance ramp from Union Road starting at 9 a.m. Monday, July 12, weather permitting.

The ramp closure will continue until the end of September, according to a news release. The ramp closure is needed for the construction of the new Union Road bridge.

Motorists are advised to use the northbound I-55 entrance ramp at Reavis Barracks Road as a detour.

The far left lane on both northbound and southbound Interstate 55 at Union Road will remain closed until mid-July for construction of the new bridge support beams in the median of Interstate 55.

This bridge work is part of a project that consists of the demolition or replacement of four bridges between Lindbergh and 4500 South Broadway, as well as upgrading the interstate lighting and the signals at Loughborough.

Specifically, the work includes:

• Removing and replacing the two Union bridges over Interstate 55. These bridges will be built in the same location with a higher clearance

over the interstate to meet current Federal Highway Standards.

• Removing the pedestrian bridges on Interstate 55 north of Delor and

north of Holly Hills.

• Replacement of the existing interstate lighting along Interstate 55

• Replacement of the signals at Interstate 55 and Loughborough
