​Work Requires Overnight Lane Closures on Capital Beltway; Intermittent Traffic Stops on MD 450

(December 10, 2021) –The Maryland Department of Transportation State Highway Administration (MDOT SHA) will make repairs to the bridge deck on Inner and Outer Loop of  I-95/I-495 (Capital Beltway) over MD 450 in the New Carrollton area of Prince George’s County starting Sunday night.   

To perform the repairs, a traffic pattern shift from four lanes to one lane will be implemented on I-95/I-495 Sunday, December 12 through Friday, December 17 during overnight hours only, 8 p.m. to 5 a.m. the next day. The lane closure schedule is as follows:

• 9 p.m. - Single lane closure.   
• 10 p.m. - Second lane closure.   
• 11 p.m. - Third lane closure.   

At least one through lane and all ramp lanes will remain open to traffic.   

Crews will work during those overnight hours Sunday through Thursday to perform the deck repairs. The bridge deck repairs are expected to take five days to complete, though the traffic shift will remain in place during overnight hours through the rest of the year to allow for related work. Motorists should also expect intermittent traffic stops overnight on MD 450.   

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 slowdown in construction zones. Motorists can dial #77 on their mobile device for roadside assistance.
