The State Highway Administration will temporarily close the northbound and southbound Interstate 95 ramps onto the Inner Loop of the Beltway south of Baltimore as part of its project to improve the flow of traffic at one of the region's busiest and most congested interchanges.
Both ramps will be closed Sunday and Monday at 11 p.m. and will reopen by 5 a.m. the following day. A detour, using the eastbound Beltway to Hollins Ferry Road, will be in place.
The highway agency said its contractor is expected to complete its widening of the current single-lane ramps to westbound Interstate 695 by late October. Currently the left-lane ramp from northbound I-95 and the right-lane ramp from the southbound highway merge into a single lane — causing traffic to back up into the travel lanes during peak travel hours.
The $3 million interchange improvement project will add a second lane feeding into the Beltway traffic at the merge point. Meanwhile, engineers are reconfiguring westbound Beltway traffic so that it goes from three lanes into two before vehicles reach the interchange, making it easier for the I-95 traffic to merge.
The SHA said at about 7 p.m. Monday it will permanently close one westbound Beltway lane approaching the interchange to give motorists time to adjust to the new traffic pattern.
