Major Bicycle Safety Improvements Coming to MD 187 (Old Georgetown Rd) in North Bethesda

by Patrick Herron

The Maryland Department of Transportation State Highway Administration (MDOT SHA) has started a project to significantly improve safety for bicyclists and motorists on nearly two miles of MD 187 (Old Georgetown Road) in North Bethesda. The improvements on MD 187, between south of I-495 (Capital Beltway) and Nicholson Lane, will convert one travel lane in each direction in order to add buffered bicycle lanes and the installation of flex posts to outline the new bicycle lanes. The new buffered bike lane will include green pavement markings as well. 

“We appreciate the feedback from community members, elected officials and other stakeholders as we worked to make this vital corridor safer,” said MDOT Secretary James F. Ports, Jr.   “These improvements on Old Georgetown Road underscore our commitment to a safe, accessible and multimodal approach to our roadways.”

The safety improvements are part of the resurfacing project that began earlier this month. The overall project will be complete by the end of the year, weather permitting.

In addition to the new buffered bike lanes, other changes underway on MD 187 include:
  • Installation of high visibility or Continental crosswalk markings.
  • Reduction of the number of travel lanes from three lanes to two lanes in each direction.
  • Narrowing the remaining 11-foot travel lanes to 10.5 and 10 feet.
  • Resurfacing and restriping of the roadway.

​“Our top priority is always to make sure our customers reach their destinations safely,” said MDOT SHA Administrator Tim Smith. “We ask that motorists obey all of the rules of the road and be extra vigilant when bicyclists are on the road. We are committed to ensuring that our roadways are safe for everyone, regardless of their mode of transportation.”

Motorists can expect single-lane closures on MD 187 weekdays from 9 a.m. to 3 p.m., and multiple lane closures from 8 p.m. to 5 a.m., Sunday nights through Friday mornings. Motorists will be guided through the work zone with cones, barrels and arrow boards. With approximately 40,000 vehicles per day use this road, drivers should plan extra commuting time during construction.

Maryland’s Move Over Law requires motorists to make a lane change or slow down when approaching any stopped, standing, or parked vehicle displaying hazard warning lights, road flares, or other caution signals. The expanded law is in place to protect emergency responders and all motorists who encounter a roadside emergency.​

​​​​​​Motorists in need may dial #77 on their mobile device for roadside assistance.
