Drivers on Interstate 270 northbound in Montgomery and Frederick counties, Maryland will now encounter new metered ramps at 16 entrance points. The ramps will regulate the flow of traffic onto the busy highway, with lights signaling when cars can enter, in an effort to reduce congestion and speed up commutes.

Why it matters

I-270 is a major commuter route in the region, with up to 260,000 vehicles using the roughly 34-mile stretch each day. Transportation officials hope the new metering system will help alleviate the chronic traffic jams that plague the highway, especially during peak travel times.

The details

The metered ramps will operate between 4 a.m. and 11 p.m. daily, using a system of flashing yellow and red lights to control the flow of traffic entering the highway. MDOT claims the new system could save some northbound drivers up to 30 minutes on their morning commute. Similar metering has already been in place on the southbound side of I-270 for about five years.

  • The new metered ramps on northbound I-270 went into effect on February 24, 2026.
