Gov. Hogan Announces $129.6 million for Watkins Mill Interchange



Governor Larry Hogan was in Montgomery County today to announce a $229.6 million plan to reduce congestion along the I-270 corridor.

Hogan made the announcement at Park Potomac along I-270 in Rockville. In keeping with the administration’s efforts to advance long-overdue highway projects, Hogan unveiled $100 million in new funding for the I-270 Innovative Congestion Management Project to improve travel times throughout the I-270 corridor. In conjunction with the corridor project, the Maryland Department of Transportation’s State Highway Administration will construct a new $129.6 million interchange at I-270 and Watkins Mill Road to reduce congestion on local roads and improve safety for residents and commuters.

“Our administration is committed to finding the best ideas that offer real solutions, and I’m excited to see innovation in action when it comes to solving the problem of congestion on I-270,” said Hogan. “We are calling on the most creative minds in the transportation industry to step forward, as we continue our investment in critical infrastructure projects that will help citizens in Montgomery County, and all across our state.”


The Watkins Mill Interchange had become a political yo-yo last year. The interchange was slated to begin in the spring of 2016 with an estimated completion date of sometime in 2018, but funding for the interchange was pulled by the Hogan and state in the fall of 2015.

Today, Hogan announced that the new I-270/Watkins Mill interchange project will be advertised in spring 2017 and start construction next summer. The $129.6 million project will support economic development and reduce congestion at the nearby I-270/MD 124 interchange and MD 355/MD 124 intersection to the south. The new interchange also will provide access from I-270 to the Metropolitan Grove MARC station. This section of I-270 now carries 166,000 vehicles a day and is estimated to grow to 235,000 vehicles a day by 2035.
