Yes No

The existing accident rate with the nonstandard feature is lower than the statewide accident rate. No increases in accident rates, severity, and costs are expected due to the nonstandard feature. The application of the proposed mitigation measures including: additional signage, pavement markings, improved lighting and the attendant crash reduction factors would decrease the crash rate at this location to 0.211 acc/mvm.

$ 150 Million $ 50 Million

Provide additional signage, pavement markings and improve lighting on the bridge.

Adjacent segments will have standard 12' lanes. Retaining 11' lanes at Bronx River Drawbridge will not have adverse impact on future drawbridge plans. Investigate the use of pedestrian bridges parallel to existing to provide wider vehicle lanes.

Providing 12' lanes and shoulders will require bridge replacement including: mechanical equipment, existing abutments and providing adequate navigational clearance. Properties and parks access will be impacted. Retaining existing bridge structure will have no adverse impact to any demographic characteristics of the area. No impact to existing wildlife and marine life in the Bronx River.

Recommend retaining existing lane width at drawbridge and transition to adjacent segments. Recommend to provide additional signage and pavement markings.

The existing accident rate with the nonstandard features is lower than the statewide accident rate. Increasing the right shoulder width to the standard value where possible is expected to decrease accident rates, severity, and costs in these sections. The crash reduction factor associated with the shoulder widening is expected to reduce the accident rate to 0.479 acc/mvm.

$500 Million Not applicable

Primary purpose of project is to improve access to Hunts Point Food Distribution Center and to rehabilitate existing expressway (including deck replacement and repairs). Widening of existing structure to meet standard for shoulder widths would not be feasible due to physical constraints (private property, buildings, railroad tracks, etc.) on both sides of the expressway. Provide support for breakdowns and emergencies through incident management system (VMS/ITS), standby oncall towing service.

Bridge structure is compatible with adjacent segments. Widening of structures would impact future plans to build a Metro North Station by Hunts Point Ave.

Widening of the bridge structure will impact adjacent railroads (Amtrak - Northeast Corridor, CSX and NYCT #6 line). Modification of existing piers will impact Bruckner Blvd below, which includes a bicycle facility.

Maintain existing bridge width with proposed shoulders of 4ft left and 4ft-6in right shoulder widths from E141st Street to Tiffany Street. Provide 4ft left and standard 10ft right shoulder from Tiffany Street to Bruckner-Sheridan Interchange. Provide 0 ft left and 8 ft right on EB direction and 8ft left and 0ft right WB direction at Bruckner-Sheridan Interchange. No shoulders on drawbridge see non-standard justification on lane width for drawbridge. Proposed 0 ft left and 6 ft right shoulders on the Bronx River Ave Viaduct.

The existing accident rate with the nonstandard feature is lower than the statewide accident rate. Increasing the horizontal curve radius and shoulder width at the sharp curve would improve stopping sight distance. The proposed mitigation to increase stopping sight distance is expected to decrease accident rates, severity, and costs at this location, resulting in a projected accident rate of 0.583 acc/mvm after application of the appropriate crash reduction factor.

$ 700 Million Not applicable

Primary purpose of project is to improve access to Hunts Point Food Distribution Center and to rehabilitate existing expressway (including deck replacement and repairs). Widening of existing structure to meet standard for shoulder widths would not be feasible due to physical constraints (private property, buildings, railroad tracks, etc.) on both sides of the expressway. Provide advanced warning signage of sharp curve and increase shoulder width at the sharp curve to improve stopping sight distance.

Widening the expressway from two lanes to three lanes and the removal of non-redundant truss bridges will allow for continuous three lanes expressway. Rebuilding the curve and bridge over the railroads will allow for improved vertical clearance over the railroads. Proposed flatter radius, grades and wider shoulders will improve interchange safety and operations.

Achieving standard values would not be feasible due to physical constraints (private property, buildings, businesses, school, etc.) on both sides of the expressway. Achieving standard values will also impact adjacent railroads (Amtrak-Northeast Corridor, CSX and NYCT #6 subway line).

Project goal is to provide 6 continuous lanes from Hunts Point Ave to Whittier Street along with reconfiguring the Bruckner Sheridan interchange to remove the left hand entrance ramp. Several improvements are proposed including flatter horizontal curvature, wider shoulders, improved Sight distance, improved grades, removal of non-redundant truss bridge and improved vertical clearance over the railroad.

The existing accident rate with the nonstandard feature is lower than the statewide accident rate. No increases in accident rates, severity, and costs are expected due to the nonstandard feature. The application of the proposed mitigation measures including: additional signage, pavement markings, and improved lighting and the attendant crash reduction factors would decrease the crash rate at this location to 2.05 acc/mvm.


Provide additional signage, pavement markings and improve lighting on roadway. A proposed share used path to be constructed along the median of Bruckner Boulevard from Southern Boulevard to Lafayette Avenue and on the west side of Bruckner Boulevard from Whitlock Avenue to Bronx River Avenue.

Adjacent and existing segments do not have shoulders. Retaining features will not have any impact on adjacent segments.

Widening of the roadway will impact parking lanes , requiring removal of travel lanes and/or parking impacting businesses access requiring parking and/or loading areas. Sidewalk and pedestrian access may be impacted as well. Modifications to Bruckner Expressway Viaduct substructure may be required as columns are located on the median of Bruckner Blvd.

Recommend retaining existing roadway width. Recommend to provide additional signage and pavement markings.

The existing accident rate with the nonstandard features is lower than the statewide accident rate. Increasing the horizontal curve radius would improve stopping sight distance and is expected to decrease accident rates, severity, and costs at this location, with an anticipated accident rate of 0.313 acc/mvm after application of the improved sight distance crash reduction factor.

$ 120 Million Not applicable

Provide advanced warning signage of sharp curve similar to existing conditions, however the proposed HSSD will be improved from existing condition.

Rebuilding the bridge over the railroads to provide adequate clearance over the railroad.

Achieving standard values will impact adjacent railroads (Amtrak-Northeast Corridor and CSX) Severe ROW impacts will occur affecting several businesses and a school.

Improve clearance over the railroad. Provide several improvements to the sharp curve and bridges over the railroad.
