Public outreach

This work covered two projects to improve traffic flow and function at the signalized intersection of Route 11 and Route 661. This project is in the vicinity of Route 37 and the Interstate 81 interchange at exit 317 in Frederick County.

The Route 11 project added southbound capacity by widening to the median to provide an additional southbound through-lane between I-81 and the Route 37 bypass. The project also reconstructed the left turn lanes. The additional through-lane provides a dedicated lane for Route 11 and Route 37 traffic, while traffic using the new center lane has the option of taking either Route 11 or Route 37.

The Route 661 project added a dedicated left-turn lane from southbound Route 661 onto northbound Route 11, while maintaining the existing Route 661 right-turn lane and dual lanes for through and left-turns.

During the design phase, Route 11 had an average daily traffic count of 36,000 vehicles per day, which is projected to increase to 49,700 vehicles per day by the year 2037. Route 661 had an average daily traffic count of 4,200 vehicles per day, which is projected to increase to 5,508 vehicles per day by the year 2037. The Frederick County bicycle plan identifies both roads as providing bicycle lane facilities.

*This project was selected for funding under SMART SCALE, the new prioritization process as outlined in House Bill Two.  Click here for more information on the prioritization process.

Benefits 

On Route 11 the additional through-lane will provide a dedicated lane for Route 11 and Route 37 traffic with the new center lane having the option of taking either Route 11 or Route 37.

On Route 661 the construction of the additional turn-lane will increase the capacity of the intersection to accommodate left-hand turns.
