Long-Term Traffic Split on Bridges over Little Gunpowder Falls to Begin July 17​ 

​​(July 6, 2022) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) is continuing its $32.6 million rehabilitation of four bridges along eastbound and westbound US 40 (Pulaski Highway) between White Marsh in Baltimore County and Joppatowne in Harford County, and will install a long-term traffic split on two of the four bridges on Sunday, July 17. The work is delayed from July 10.​

Weather permitting, crews will work from 7 p.m. Sunday, July 17, to 5 a.m. Monday, July 18, to set up barriers that will divide two travel lanes on eastbound US 40 over Little Gunpowder Falls (toward Aberdeen) and on westbound US 40 over Little Gunpowder Falls (toward Baltimore).

The shift will be in effect for approximately five months to allow crews to safely work on both bridge decks this summer and fall. The entire project is expected to be complete by spring 2023, weather permitting. MDOT SHA contractor Allan Myers – MD Inc., of Fallston, is performing the work.
