Route 100C Bridge Replacement Project Begins in Mount Pleasant
Work began last week on a nearly $14 million state Department of Transportation (DOT) project to replace the Route 100C bridge and create a roundabout in Mount Pleasant.
State DOT Acting Commissioner Paul Karas said plans call for the removal and replacement of the bridge carrying Route 100C over Route 9A and construction of a new roundabout at the intersection of Route 100C, the Route 9A southbound ramp and Old Saw Mill River Road in Mount Pleasant and Greenburgh. The project will improve efficiency and enhance safety for motorists, bicyclists and pedestrians along Route 100C, Karas said.
“The replacement of this bridge and construction of a new roundabout in this location will both enhance safety and improve the flow of traffic at a location that provides an important connection to major employers, medical facilities and higher education institutions,” Karas said.
Preparation, survey and utility work will continue into the fall, but much of the construction work, which will involve the closure of the Route 100C bridge and a detour for Route 9A, is anticipated to begin next spring, the DOT announced last week. The bridge closure will be announced in advance with construction expected to be completed in November, 2019.
The thoroughfare is a popular route for motorists heading to Westchester Community College, Westchester Medical Center, New York Medical College, Blythedale Children’s Hospital and several Westchester County facilities.
Built in 1936, the current span is an arched concrete structure with two travel lanes and one turning lane. It will be replaced with a steel multi-girder bridge that will contain two travel lanes, one turning lane and 10-foot-wide shoulders and five-foot-wide sidewalks on both sides of the bridge, according to the DOT.
The roundabout will replace an intersection now controlled by traffic signs.
Congresswoman Nita Lowey (D-Harrison) lauded the project.
“These much-needed improvements should also significantly help the traffic flow at this busy transportation link,” Lowey said.
Messages left last week for Mount Pleasant Supervisor Carl Fulgenzi were not returned.
