Project Letting - October 2016
This project was initially the full replacement of a bridge carrying mainline Turnpike over Brush Creek. The project modified the scope for a superstructure-only replacement project, incorporating ABC strategies. The existing superstructure is a two span non-composite adjacent box beam bridge with two lanes in each direction and relatively narrow shoulders. SPK developed final plans for a two span continuous steel superstructure which minimizes the impacts to the Turnpike traffic and utilizes the existing substructure.
This was the first ABC slide project on PTC
mainline, completed in less than 55 hours
and won the 2017 Accelerated Bridge
Construction (ABC) Annual Conference
award for best Superstructure Slide
Project in Miami, FL December 7, 2017.
