Description:

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. This bridge consists of 4 simple spans (32’ - 70’ - 70’ - 36’) on a nearly tangent alignment having a 35 degree skew.

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 weeks rather than months which would have been required for a cast-in-place deck replacement.

As the first bridge deck replacement of its type within Delaware, the panelized replacement with UHPC joints offered a significant learning curve for contractors within the state.  Throughout the project there were many lessons learned.

This presentation will walk through the decisions made during design that lead to the preferred alternative, highlight the critical ABC deck panel design details, and present construction photos and discuss construction lessons learned.

Presenters:

Jonathan R Eberle, EIT - Jon is a structural engineer within AECOM’s transportation group. He obtained his bachelor’s degree from Bucknell University in 2010 after which he completed his Master’s Thesis at Virginia Tech. He worked as the design engineer for the DelDOT BR 1-717 deck replacement project. Jon has worked on several projects in and around Delaware including projects on the Commodore Barry Bridge, Delaware Memorial Bridge and the emergency repairs to I-495 over the Christina River. He is currently working as the senior engineer for the arch span re-decking of Minnesota DOT’s High Bridge, a long span tied steel arch.

Elaine Luczka, PE – Elaine served as resident engineer for the BR 1-717 project throughout the 24/7 construction schedule.  Her work at AECOM also includes bridge design for the reconstruction of I-95 through Philadelphia as well as bridge and other structural projects throughout the mid-Atlantic region.  Ms. Luczka received a BSCE and BSAE from Drexel University in 2007, returned to complete her MSCE and serves on their Engineering Alumni Association board.  She also actively volunteers with various organizations on community building, STEM initiatives and mentorship.
