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.

Superstructure Replacement Project in Lebanon County - The existing bridge was a single span steel thru-girder bridge over two active lines of Norfolk Southern Railroad. Traffic needed to be maintained on the existing roadway so SPK studied methods to replace a thru-girder bridge in half-widths, concluding with a design for a steel girder support beam placed near the deck cut line with hangars detailed to support the severed floorbeams. The grade was being increased as well to improve the railroad underclearance.
