Work is expected to start this summer on a project to widen a portion of Md. 180 near Frederick, which will add a second bridge over U.S. 15, as well as make the area friendlier for bicyclists and pedestrians.
No specific date has been set for the project to begin, but it should start sometime this summer, State Highway Administration spokeswoman Shantee Felix said in an email Monday.
The $21 million project should be finished by summer 2021.
The project will widen Md. 180 from west of Swallowtail Drive to Interstate 70, as well as build a second two-lane bridge over U.S. 15 near Butterfly Lane. It will also add bicycle and pedestrian routes over the bridge and throughout the project area, and a new left-turn lane at Solarex Court.
The current bridge was named in 2016 for Marine Sgt. David James Smith, who died in Germany from injuries suffered in a suicide bombing in Afghanistan in January 2010.
During the work, there will be a barrier with a lane shift where U.S. 15/U.S. 340 will travel under Md. 180, and a barrier along Md. 180 east of the U.S. 15 ramp.
Drums will guide drivers through shoulder work on Md. 180 from west of the U.S. 15 ramp to the project limits.
That section of Md. 180 is used by about 22,000 vehicles per day, according to SHA.
The work is part of several projects on Md. 180.
Last week, the intersection of Md. 180 and Mount Zion Road was closed until December for the construction of a roundabout in an attempt to reduce crashes at the juncture.
In 2017, work was completed on a project to widen Md. 180 near Solarex Court.
That project added a 5-foot-wide paved bicycle and pedestrian path along westbound Md. 180 between Solarex Court and Ballenger Center Drive.
