US 15 SignCrews Temporarily Closing Left Lane to Complete Bridge Deck Replacement January 17, 2023) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) will shift travel lanes on the northbound US 15 bridge over MD 77 (West Main Street) in Thurmont on Friday, January 20, as part of the ongoing US 15 bridge rehabilitation project. Crews have installed a new bridge deck on the right lane and on Friday will shift traffic onto that side of the northbound US 15 bridge. Starting at 8:30 a.m., crews will open the right lane on the new northbound US 15 bridge. At the same time, crews will close the left lane they can begin the bridge deck replacement on that side. All work is expected to be complete by 5 p.m. Friday. MDOT SHA contractor Clearwater Construction Inc. will use electronic signs, barrels and cones to alert motorists about the traffic pattern change. MDOT SHA reminds motorists the speed limit through the work zone on the northbound US 15 bridge is 55 mph. 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. Please drive like you work here and slow down in construction zones. The project to replace the bridge deck under the roadway started in December 2021 and is expected to be complete by the end of this year. Learn more about the project by clicking here.
