Hogan Administration Announces Planned Improvements to I-270 in Clarksburg



The Hogan administration is taking the next step of the $100 million I-270 Innovative Congestion Management (ICM) Project in Montgomery and Frederick counties, which will save drivers up to 30 minutes on their morning commute from Frederick to I-495 when the project is complete.

The Maryland Department of Transportation State Highway Administration (MDOT SHA) will remove the top layer of asphalt, pave and restripe a nearly eighth of a mile section of southbound I-270 approaching the dual exit lanes to I-370 to improve access to the exit lanes.

Additionally, MDOT SHA will mill, pave and restripe to extend the outside southbound I-270 deceleration lane to MD-80/Fingerboard Road, the MD-80 acceleration lane to southbound I-270 in Frederick County and the acceleration lane from MD-109/Old Hundred Road in Clarksburg to southbound I-270.

All of the work is anticipated to be complete by the beginning of 2019.

“We are moving forward on these transformative projects to relieve the congestion problems on I-270,” said Governor Larry Hogan. “Getting these critical infrastructure improvements done is important to Montgomery County and Frederick County, along with all of our local jurisdictions and economic development statewide.”

The current lane configuration of I-270 at I-370 includes four through lanes and two dedicated right exit lanes to I-370. Upon completion of this part of the I-270 ICM project, four through lanes on southbound I-270 will be preserved, but the innermost dedicated turn lane to I-370 will be converted to a ramp lane/through lane option, providing drivers with improved access to the exit to I-370.

“Innovation is key to providing real benefits to Maryland motorists, as this project demonstrates,” said Transportation Secretary Pete K. Rahn.

Most of the work will take place at night with single lane closures on southbound I-270 at MD-80 in Frederick County between 8:00 pm and 4:00 am, Monday through Thursday. Single lane closures on southbound I-270 at MD-109 in Montgomery County will take place between 10:00 pm and 5:00 am, Mondays through Sundays.

Double and triple lane closures will take place on southbound I-270 at I-370 in Montgomery County between 8:00 pm and 5:00 am, and occasional single lanes closures will be necessary Mondays through Sundays between 10:00 pm and 8:00 pm.


Approximately 225,000 vehicles use this section of I-270 each day, so motorists should provide extra travel time during active construction.
