RIDGE HILL INTERSECTION-TRAFFIC SAFETY IMPROVEMENTS


When it became clear to Greenburgh, Ardsley & Hastings officials that we could not legally stop the RidgeHill development from being approved by Yonkers we entered into an agreement with the city and Ridge Hill developers. Ridgehill would contribute $5 million towards road improvements. A committee made up of representativers of Greenburgh, Ardsley & Hastings has been meeting. This committee has been reviewing various traffic safety options.This is a summary of the committees most recent meeting, as reported by Thomas Madden, Commissioner of Planning.
PAUL FEINER

At the March 19, 2009, Ridgehill Intersection Improvement Committee, discussed and classified the twelve project study areas into three categories, in order better allocate resources when studying the intersections and road segments. These categories are 1) Intersections that would benefit from further study and have the most impact; 2) Intersections or improvements that should be sent to the State or County as a report and analysis for future road work considerations; and 3) No improvements needed until 2028.



Category A: Intersections that would benefit from further study



1) Route 9A and Jackson Avenue

a) Suggested improvements

It is proposed to add an exclusive left-turn lane to all approaches and to add an exclusive right-turn lane to the northbound approach, so that the southbound, eastbound, and westbound approaches would consist of a left turn lane and a through/right turn lane, and the northbound approach would consist of a left turn lane, a through lane, and a right turn lane. The traffic signal would also be improved.



2) Jackson Avenue and South Sprain Road

a) Suggested improvements

It is proposed to add an exclusive left turn lane to the northbound approach, and to add a right turn lane to the eastbound approach. So that the northbound approach would consist of two left turn lanes, and a right turn lane. The eastbound approach would consist of a right turn lane and a through lane, and the westbound approach would consist of a left turn lane and a through lane. The traffic signal would also be improved.



3) Jackson Avenue and North Sprain Road

a) Suggested improvements

The installation of a traffic signal along with a realignment of the intersection to a typical T-intersection will eliminate the delays at this intersection.



4) Route 9A and Ashford Avenue

a) Suggested improvements

It is proposed to add one additional through lane to each the southbound, westbound, and eastbound approaches, along with the required signal improvements to improve the operation of this intersection. This major improvement will require considerable study due in part to the fact that there is little available land for the improvements.



5) Widening of Route 9A between Ashford Avenue and Heatherdell Road

a) Suggested improvements

Study in conjunction with Route 9A and Ashford Avenue to widen the road and straighten horizontal and vertical curves.



Category B: Intersections or improvements that should be sent to the State or County as a report and analysis for future road work considerations.



1) Jackson Avenue and Southbound Sprain Brook Parkway Ramps

a) Suggested improvements

It is proposed to add an additional southbound exclusive left turn lane. The southbound double left with the required signal improvements will improve the operation of this intersection.



2) Jackson Avenue and Northbound Sprain Brook Parkway Ramps

a) Suggested improvements

Redistributing the available green time is proposed to improve the operations at this location.



3) Sprain Road and Ardsley Road/Ashford Avenue

a) Suggested improvements

The installation of a traffic signal along with a realignment of the intersection is recommended. It is proposed to add an eastbound left turn lane and a westbound left turn lane. The horizontal and vertical curves must be closely studied to determine how much the slope of Ardsley Road must be modified in order to allow for safe stopping during inclement weather, as this is anticipated to be the greatest issue with the addition of a traffic signal.

4) "S" curve along Jackson Avenue between Sprain Road and the Park

a) Suggested improvements

Look at widening the road to straighten horizontal and vertical curves.



5) Ramp from Route 9A to the NYS Thruway

a) Suggested improvements

Redesign to have two new ramps that would outlet unto 9a under current thruway bridge abutments in order to make this “urban” intersection.



Category C: No improvements needed until 2028



1) Route 9A and Lawrence Street

a) Suggested improvements

None



2) Jackson Avenue and St. Andrews Way

a) Suggested improvements

The installation of a traffic signal along with a realignment of the intersection to a typical T-intersection will eliminate the delays at this intersection.

"3) Sprain Road and Ardsley Road / Ashford Avenue"

I can think of no greater traffic safety need in southern unincorporated Greenburgh. With no snow for the next several months, PLEASE get two stop signs and two stop ahead signs installed right now. It's a town intersection, so there's no need to delay for county or state approvals. And by next winter, you can fix the slope - an annoying but not difficult task. (Of course a traffic signal would be ideal, but let's start with something easy and immediately do-able with little expense.

The police chief has conducted a study of this intersection and found that lights or signs would make the road more dangerous.

The chief is correct.
What should have been done when the house on the corner was up for sale the town should have made the purchase to make wider that intersection.

The removal of part of the slope should be considered because one cannot see the cars coming out of Sprain rd.until it's too late.

Speeding is another factor. You never see a patrol car in that imediate area. Yes you will find one sometimes by Sprain Valley rd.
And when the greenery starts to develope you may find one by the Sprain Parkway over pass.
The police should more visible to stop the speeders.

By the way Paul The chief gave you good advice too bad the others in this town are not doing the same.

Smarten up buddy .

frustrated said...

so nothing can be done to improve the sight lines?

and to think the gel sprain development just up the road will add 30 luxury homes with at least 2cars each!!

lets stop hearing what cannot be done

lets start hearing what CAN be done.

help needed said...

hi
im a traffic signal looking for a job
can you help me?

Take a drive around town said...

Paul since you supposely drive around town. I was wondering if you have noticed numerous telephone poles cut with caution tape and yellow rope tied to trees supporting them so they do not fall on the road. IF you haven't please drive along Dobbs Ferry Rd (route 100B). I counted 3. Another accident waiting to happen.

big fix needed said...

paul
why not fix or replace all the damaged and faded street signs?

the boy scouts could inventory them and you could direct dpw to make the improvements.
