A major construction project on Interstate 95, set to begin Sunday, will impact traffic in Baltimore for the next two years — shifting and narrowing lanes and forcing ramp closures and detours.
The $66 million project to remove and replace the existing concrete deck and roadway joints of 4.4 miles of the elevated highway between Caton Avenue and the Fort McHenry Tunnel south of downtown is expected to last through the middle of 2016, the Maryland Transportation Authority said Friday.
While lane closures will be restricted to off-peak hours when major events are not scheduled, lanes will be reduced from 12 feet in width to 11 feet in width and shoulders will be eliminated in some areas.
The work, which will also include repairing and replacing drainage troughs, milling and resurfacing of bridge decks and "miscellaneous structural repairs," will be conducted by G.A. and F.C. Wagman, Inc., of York, Pa. It will be funded entirely with toll revenues, the MdTA said.
On Sunday, weather permitting, lanes of northbound I-95 will shift to the right shoulder, and concrete barriers will be installed later this month or early next month, the MdTA said.
In early May, lanes of southbound I-95 will shift to the right after concrete barriers are installed.
For about three months this summer, the ramp from southbound Interstate 395 coming out of the city will be reduced to one lane. The ramp will be reopened at full capacity before school begins again in August, the MdTA said.
At various times during the project, other ramps will be subject to closures lasting between one and two weeks. Those are the ramps connecting McComas Street to I-95, Washington Boulevard to southbound I-95; Route 295 to northbound I-95; northbound I-95 to Hanover Street; Hanover Street to southbound I-95; and northbound I-95 to Key Highway.
Other ramps will be subject to part-time closures, including the ramps connecting southbound I-95 to northbound I-395; southbound I-395 to northbound I-95; southbound I-95 to southbound Route 295; Russell Street to southbound I-95; northbound I-95 to Russell Street; and southbound I-95 to Caton Avenue.
Portable and overhead electronic signs will be used to share detour information, the MdTA said.
While bridges along I-95 north of the tunnel were resurfaced in 2001 and 2004, this will be the first resurfacing along I-95 south of the tunnel since the tunnel opened in 1985, the MdTA said.
