Presentation Topic: Bridge 1-717 Accelerated Bridge Deck Replacement using Precast Panels

As the major artery between Baltimore and Philadelphia, Interstate 95 carries large volumes of traffic through northern Delaware. With a current ADT of 85,000, Bridge 1-717 carries four lanes of Interstate 95 Northbound over Rt. 7/ Rt. 1, the major North-South route in Delaware. When the bridge deck began to deteriorate and the decision was made that a replacement was required, DelDOT quickly determined that the high traffic volumes carried by the bridge made this project a prime candidate for ABC techniques. Of several ABC alternatives investigated, full-depth precast panel replacement using UHPC transverse and longitudinal joints with a polyester polymer concrete (PPC) overlay was selected as the preferred alternative. Through phased construction, this alternative allowed work to be completed while maintaining 3 lanes of traffic open at all times and the duration of on-site work to be limited to 38 days rather than 5 months which would have been required for a cast-in-place deck replacement. This presentation will walk through the decisions made during design that lead to the preferred alternative and highlight the critical ABC deck panel design details by the designer in addition to the presentation of construction photos and discussion of construction lessons learned by DelDOT.

Attendees at this meeting will earn 1.0 PDH!
