Motorists who normally take the northbound Ritchie Highway exit to I-695 west and I-895 will have to use alternate routes this week, State Highway Administration officials said.
The ramp will be closed from 8 p.m. to 6 a.m. tomorrow through Friday while it is patched and resurfaced. Motorists should watch for signs and traffic barrels to guide them around the work area, officials said.
Motorists wishing to get to I-695 west from the northbound lanes of Ritchie Highway should take Route 710 east (Ordnance Road), situated just before the ramp closure south of the Motor Vehicle Administration building, to Route 10 north.
The Harbor Tunnel road, I-895, can be reached if motorists continue driving north on Ritchie Highway and take the exit ramp at Patapsco Avenue, officials said.
