Commissioner Thomas Madden of the Planning Department sent me the following memo concerning improvements that have just started on Jackson Ave and Saw Mill River. A new left turn lane—and traffic signal upgrades!
PAUL FEINER
1) Jackson Avenue and Route 9A (Saw Mill River Road)
The developer is currently constructing improvement to the Jackson Avenue and Saw Mill River intersection. The proposed improvements include new drainage facilities around the intersection, to widen all approaches to the intersection and to add exclusive left-turn lanes and to upgrade the existing traffic signal.
2) Jackson Avenue and “S” Curve Between Sprain Road and the Park
As part of the settlement with the developers of Ridgehill, the Ridgehill Intermunicipal Intersection Committee’s consultant is currently designing improvements to straighten out this roadway segment through alignment improvements and to increase the roadway vertical and horizontal radii in order to address design speed criteria.
3) Jackson Ave. & North Sprain Road
As part of the settlement with the developers of Ridgehill, the Ridgehill Intermunicipal Intersection Committee’s consultant is currently designing improvements to reconstructed the intersection by eliminating the existing triangular island and re-align North Sprain Road to meet Jackson Avenue at a typical T-type intersection. This improvement would required a traffic signal be installed to control traffic. With the intersection reconstruction, the eastbound approach would consist of one through lane and one left-turn lane, the westbound approach of one through lane and one right-turn lane, and the southbound approach of one right-turn lane and one left-turn lane. Town of Greenburgh DPW is coordinating the proposed improvements to the Drainage District at this intersection.
4) Route 9A (Saw Mill River Road) and Ashford Avenue
As part of the settlement with the developers of Ridgehill, the Ridgehill Intermunicipal Intersection Committee’s consultant is currently designing improvements to the intersection to match up with the proposed improvements (2014-2015) by the County to the existing bridge. The proposed improvements include widening of the intersection to match the proposed widening of the bridge lanes and redesign of the existing turning and through lanes to accommodate the existing and future traffic conditions.
5) Route 9A (Saw Mill River Road) from Ridge Road/Bridge Street to Heatherdell Road
As part of the settlement with the developers of Ridgehill, the Ridgehill Intermunicipal Intersection Committee’s consultant is currently designing improvements to this roadway segment that will include proposed roadway widening and a possible center left hand turn lane to access businesses along the road, sidewalk and landscaping improvements.
The improvements numbered two thru five are in the design phases and plans are expected to be completed within the next year and half with construction proceeding right after the plans have been approved
