Project Details:

• Two existing prestressed concrete girder bridges with concrete pier caps and abutment seats bearing on HP piles.

• Bridges on horizontal curve, resulting in variable span lengths and bridge width.

• Six spans of variable length; 83’-10” to 88’-0”.

• Bridge width average of 54’ for two lanes of traffic.

• Girder number and spacing varies from span to span.

• Rehabilitation design to:

  • replace bridge deck and barrier railings.

  • convert existing simply supported bridge to continuous for HS-20 live loading.

  • due to irregular spacing of girders, no pier diaphragms will be used.

  • detail to break bond between the girders and deck at the piers will be used to allow deck continuity.

  • replace/repair concrete at abutment diaphragms, pier caps and wingwalls.

  • construct new approach slabs.

  • replace existing bearings and reuse existing girders.

  • provide new bridge joint seals at deck slab.

  • install new drainage rundowns and deck drains
