Hylan Boulevard Bridges Rehabilitation Design


HAKS provided project scoping and preliminary/final design services to the New York State DOT for the $10 million rehabilitation of two bridges that provide a major route for vehicles and pedestrians over the Staten Island Expressway near the Verrazano-Narrows Bridge. The two-span, steel multi-girder bridges have concrete decks and asphalt-wearing surfaces.

The rehabilitation involves replacement of the bridge decks with a new, reinforced isotropic concrete deck as well as new armorless bridge joints, approach slabs, bridge sidewalks with parapet, single-slope bridge barriers, lampposts, and pedestrian fencing. The superstructure steel and substructures will remain, with localized concrete repairs performed at the abutments and piers. At the northbound bridge, bearings will be replaced with new, elastomeric bearings and the pedestals will be reconstructed. Utilities embedded within the sidewalk of the bridges will be relocated and supported between superstructure steel below the new bridge decks. Approach roadways will be milled and paved to the service road intersections; approach sidewalks and curbs will be replaced; and approach guide railing transitions to the new bridges will be installed.

Services included preparation of project scoping and design reports and contract bid documents along with all engineering design services for structural, highway, utility, drainage, and traffic disciplines.  The high-profile project requires public outreach and coordination with city agencies, utility companies, and MTA Bridges and Tunnels. HAKS is currently providing construction support services.
