KEENE — The State Department of Transportation is warning motorists that construction will begin this Wednesday on a project to make slope repairs along Route 73 in the vicinity of Cascade Lakes between Lake Placid and Keene.
Then, starting on May 1, traffic will be reduced to one lane there, with a temporary traffic signal to control alternating one-way traffic from Lower Cascade Lake to approximately a half-mile east of Bobsled Run Road.
The lane closure will be in effect through May, with construction completed and all lanes open to traffic before Memorial Day weekend, a press release said.
The road may be fully closed for up to 30 minutes at a time for boulder removal and rock-scaling operations, which could present hazards to passing traffic.
Three parking areas will also be closed during construction, at Stagecoach Rock, Cascade Mountain and Pitchoff Mountain.
The parking area for Cascade Mountain is one of the most used in the Adirondack Park.
At some point during construction, Route 73 will be closed completely for one weekend, between 6 a.m. Saturday and 6 p.m. on Sunday. This weekend closure will occur May 11 through 12, depending on weather and work schedule. The final dates will be announced to the traveling public in advance.
During the closure, traffic will follow a signed detour along routes 86 and 9N, Springfield Road (County Road 83) and Fox Farm Road (County Road 63).
The dates of the repairs were scheduled in cooperation with local municipalities to avoid the busy summer and fall tourist seasons, DOT said.
During construction, motorists will find long delays and should consider alternate routes, the agency said.
