​Work will Enhance Safety and Improve Traffic Operations 

(July 12, 2021) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) is beginning work today on intersection improvements at MD 108 (Clarksville Pike) and Centennial Lane/Beaverbrook Road in the Columbia area of Howard County. The $8.2 million project is expected to be complete in fall 2022, and will include:

  • Widening both directions of MD 108 approaching Centennial Lane/Beaverbrook Road to accommodate new turning lanes at the intersection and new bicycle lanes.
  • Constructing a new, second left-turn lane from eastbound MD 108 to Centennial Lane.
  • Extending the right-turn lane on westbound MD 108 by approximately 350 feet.
  • Widening Centennial Lane to accommodate the new double left-turn lanes.
  • Upgrading the pedestrian signal and crosswalk.
  • Improving area drainage systems.
  • Installing a new traffic signal for the new turn lanes.

“The intersection of MD 108, Centennial Lane and Beaverbrook Road is an important connection in the Columbia community serving local motorists, commuters, bicyclists and pedestrians,” MDOT Secretary Greg Slater said. “These improvements will enhance safe operations and make the intersection more accessible for all.”

During construction, MDOT SHA’s contractor, Kibler Construction Company Inc. of Finksburg, will conduct occasional single-lane closures and flagging operations from 9 a.m. to 3 p.m. Monday through Friday. MDOT SHA will use electronic message boards, signs and cones to alert motorists and guide them through the work zone.   

Intersection pedestrian access will be maintained throughout construction. However, the Centennial Park trail entrance located at the MD 108 intersection up to the trail split (approximately 400 feet) will be closed during the project's duration. There will also be no parking permitted along the Centennial Lane shoulders to ensure safety inside the work zone. Learn more about this project on MDOT SHA’s Project Portal by clicking HERE.

"This project is a great example of how partnerships between state and county agencies can improve our transportation network and enhance safety for the community,” MDOT SHA Administrator Tim Smith said. “I want to thank Howard County for working with MDOT SHA to help this project move forward.”

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.
