The project will repair potholes, install planking braces to strengthen the bridge deck, patch concrete and add a new roadway surface on the bridge to improve safety. The project is expected to complete in April. The project was intially scheduled to begin Wednesday, March 2.Starting at 9 a.m. Wednesday, crews will close the right lane of eastbound US 340 past the MD 180 (Jefferson Pike) exit to install new planking braces. The lane closure will be in effect from 9 a.m. to 4 p.m. weekdays, and the planking work is expected to take approximately one week to complete. Crews will then work daily during daytime and overnight hours to make necessary concrete and surface repairs. MDOT SHA will maintain two-way traffic on the bridge with at least one travel open in each direction. However, motorists are advised to take an alternate route during the project to avoid travel delays if possible. MDOT SHA will use electronic boards, cones, barrels and signs to alert motorists about the lane closures and guide them through the work zone.MDOT SHA works hard to maintain safe traffic mobility in work zones for our crews as well as our customers. Drivers need to stay alert, focus on driving and look for reduced speed limits, as well as other driving pattern changes.
