Beginning Friday night, the Francis Scott Key Bridge service road will be closed for about two weeks, weather permitting.
Maryland Transportation Authority crews will make improvements to the road as part of a $1.6 million preservation project, according to a statement from the department.
The service road allows motorists to access Broening Highway from the Baltimore Beltway's inner loop, and provides access to the outer loop from Broening Highway, according to the statement.
"Some truckers that are on the Inner Loop and need to access the Port of Baltimore off Broening Highway would be affected by this closure," transportation authority spokesman John Sales said in an email to Dundalk Patch. "Likewise, employees working off Broening that use the Service Road to get to the Outer Loop for their ride home would also be affected."
During the closure, detour routes will direct inner loop traffic across the Key Bridge to Quarantine Road (Exit 1), to the outer loop to Broening Highway (exit 44).
A free "turnaround" pass will be issued to motorists using the detour.
Weather permitting, work will begin at 7 p.m. Aug. 16 and continue through 5 a.m. Thursday, Aug. 29.
