Construction on Mayfield roundabout started
The $1.5 million safety improvement project will change the intersection into a single-lane roundabout –a circular intersection without traffic signals that is engineered to slow traffic, maximize safety and minimize traffic delay.
Mayor Jamie Ward had said earlier this month that for increased safety measures, a temporary traffic light will be installed at the Route 30 and 349 intersection.
The Route 30 south intersection toward Amsterdam will be closed.
An official detour for traffic heading north on Route 30 will be established from Route 349 to 30A then a right to head back toward Mayfield.
The Paul Nigra Center will be accessible at the dead end of Route 30A, Ward said.
At the Route 30/30A intersection, the existing flashing traffic signal will be removed and a 130-foot diameter single-lane roundabout will be constructed.
The goal of the roundabout, according to a news release from the state, “is to address safety issues using cost effective accident reduction measures.”
State officials said constructing a roundabout would prevent vehicles from making the sharp turn at fast speeds.
The Route 30 and Route 30A intersection is known for its heavy traffic and on average, there are 11,600 vehicles, per day, that pass through the intersection. The site is also known for the number of accidents it has, which have occurred there and is double the expected accident rate of 2.8 accidents per million vehicle miles and countywide 6.21 accidents per million vehicle mile.
The New York state Department of Transportation did a 60-month study on the intersection and in that time there were eight personal injury accidents, six property damage accidents and three miscellaneous accidents.
The project is expected to be complete this fall.
“Safety is our top priority and this new roundabout will ease commercial, tourist and residential traffic by encouraging safer and smoother travel through a busy intersection,” state Department of Transportation Commissioner Marie Therese Dominguez said in the release.
She said Routes 30 and 30A “are important north-south highways, linking Great Sacandaga Lake and the Adirondack Park in the North to Gloversville, Johnstown and the city of Amsterdam in the south and beyond. The intersection is at the crossroads of a Regional Bike Route with the Adirondack Trail Scenic Byway.”
The roundabout project will include some pavement widening and upgrades to drainage and signage. Work is scheduled to be completed this fall, weather permitting.
Roundabouts are engineered to maximize safety and minimize congestion. Compared to traditional intersections, traffic flows more freely through roundabouts, reducing traffic build up and commute times. Reduced vehicle idling time means fewer fuel emissions and improved air quality. Crashes at roundabouts tend to be less severe because they typically occur at slower speeds. Roundabouts also eliminate the need for electricity-powered traffic signals.
During construction, Route 30 will be closed from its intersection with Route 349 to its intersection with Route 30A. A temporary traffic signal will be installed at the Route 30 and 349 intersection and traffic will be detoured to Route 349 and Route 30A. Route 30 will be temporarily widened to separate traffic from the highway work zone while the roundabout is being constructed.
