Improvement is compatible with future plans.

The proximity of several existing PANYNJ AirTrain piers limits the geometry between Federal Circle and Belt Parkway. The proposed horizontal alignmentaccommodates an increased roadway width through this area without impact to the AirTrain structures. Using a curve radius of 847 ft, the alignment ties the revisedtangent section through the piers back to existing in the shortest reasonable distance while maintaining current operating speeds.Upgrading mainline geometry to accommodate a 60mph speed throughout would result in significant impacts to the PANYNJ AirTrain piers and potentially to the loopand slip ramps in this area.

Construct curve with a radius of 847 ft. This proposed design corresponds to the same recommended speed as existing in this area. It is recommended to maintain thecurrent posted speed of 50mph.

Rear-end accidents may be a result of inadequate horizontal stopping sight distance. Also, improvement of the roadway by the addition of a fifth lane is expected toreduce congestion-related crashes like rear-end crashes.

$81 Million N/A

The right shoulder width and subsequently the sight distance vary along the length of this curve. The value of 495 ft reflects the minimum sight line within these limitsand meets the distance required for a 55mph speed. The right shoulder widens beyond standard just north of this curve. Further mitigation is not proposed. See othersections of this form for detail regarding limitations on achieving the standard or incorporating additional mitigation measures.


A fifth travel lane is being added to the existing mainline roadway in this area. The current proposed right shoulder width is confined by addition of that lane and theNorthbound VWE existing pavement edges. The existing mainline in this area is newly constructed under a recent Kew Gardens Interchange (KGI) contract. Proposeddesign is intended to provide VWE modifications with minimal disruption/impact to the new construction. Changing this curve to accommodate a 60mph sight linewould impact the existing retaining wall running adjacent to the right shoulder; the retaining wall is not intended to be modified or replaced by this project.

Construct curve with a minimum sight line of 495 feet. Maintain the current posted speed of 50mph.

The current accident rate is approximately the statewide accident rate. 9 crashes were reported in this segment during the three-year period. 44% of these crasheswere rear-end crashes. Improvement of the roadway by the addition of a fifth lane is expected to reduce congestion-related crashes like rear-end crashes. It is thusunlikely that the proposed horizontal stopping sight distance will significantly impact the future accident rate.

The left shoulder width and subsequently the sight distance vary along the length of this curve. The value of 430 ft reflects the minimum sight line within these limitsand meets the distance required for a 50mph speed. The left shoulder width is being optimized within the space available to accommodate improvements. Furthermitigation is not proposed. See other sections of this form for detail regarding limitations on achieving the standard or incorporating additional mitigation measures.

The Nonstandard Feature lies within a SDL (Reference Marker 1001-1005), but only one accident was recorded in the area of the Nonstandard Feature.
