MD 146 sign)Crews Will Implement a 24/7 Closure and Detour for Three Weeks (July 1, 2021) – On Monday, July 19, the Maryland Department of Transportation State Highway Administration (MDOT SHA) will begin replacing three culverts on a section of MD 146 (Dulaney Valley Road) adjacent to the Loch Raven Reservoir east of Lutherville-Timonium in Baltimore County. The culverts, which are concrete structures that carry streams under the roadway, are in poor condition and need to be replaced. When work begins at 9 a.m. on July 19, crews will implement a 24-hour, seven-day-a-week closure and detour on MD 146 between the area north of Timonium Road and south of Old Bosley Road. The $1.2 million project is expected to be complete by Aug. 9. The project was postponed from July 12.Motor carriers, motorists and bicyclists traveling between Towson and Jacksonville should follow the posted detour route: I-695 (Baltimore Beltway), MD 45 (York Road) and MD 145 (Paper Mill Road/Sweet Air Road). Motorists traveling between Towson and Jacksonville should allow extra time to travel on the detour route to get to their destinations. Area residents may see increased traffic in their neighborhoods. The intersection of MD 146 and Old Bosley Road will be open for local traffic access to and from Dulaney Valley Road north of Old Bosley Road. Additional construction work times and temporary daytime lane closures with flagging operations for two-way traffic may be necessary in the week before and weeks after the three-week detour, so crews may safely prepare and dismantle the construction work zone. MDOT SHA’s contractor, Concrete General Inc., of Gaithersburg, is performing the work. The closure, which will be in effect for all vehicles and bicycles, is needed because of the narrow width of this two-lane section of MD 146. For more information about the project, click HERE. 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. Drive like you work here and slow down in construction zones.
