Changes Discussed for Intersection
at Routes 120/133
The NYS Department of Transportation (DOT) held a second community workshop on November 6, 2008, to discuss possible changes to the intersection at Routes 120 and 133 in Chappaqua. The current “Y” intersection has poor sight lines with multiple stop signs, and can back up with long delays at Quaker Road/Route 120.
DOT staff reviewed existing conditions at the intersection and outlined objectives for the redesign of the intersection – to improve safety, reduce traffic speed, reduce waiting time, and minimize impacts on surrounding properties.
Taking into account community input from a prior workshop held a month earlier, the DOT developed four possible alternatives for the intersection. These included two featuring a T-intersection – one with a stop sign and one with traffic signals – as well as a roundabout and a “no build” option.
According to the DOT, the T-intersection with a stop sign and or traffic signals would both offer improved geometry for the intersection, but the stop sign alternative would still present significant traffic delays while not addressing traffic speed on Route 133. A signalized T-intersection would slow down traffic and improve delays, but might not reduce the number of accidents. A roundabout would reduce traffic delays, slow traffic on all approaches, and reduce the number of accidents; but it would be the most expensive option to build and would present greater right-of-way impacts, as well as issues with the grade of the road. The “no build” alternative would improve signage and sight distances with some clearing, but most of the existing problems of the intersection would remain.
The DOT anticipates its next presentation on the intersection will be at a Town Board meeting in early 2009. It's not too late to contact the DOT with your feedback. E-mail your comments to Ken Forness, Project Engineer, at kforness@dot.state.ny.us; or to Theresa Dewey, Project Public Involvement Coordinator at tdewey@dot.state.ny.us. Write to them at NYS Department of Transportation, Region 8, 4 Burnett Boulevard , Poughkeepsie , NY 12603 .
The four options are pictured below:
Option 1 No Build:
Option 2A T with Stop
Option 2B T with Signal
