I-95/SR 896 Interchange Project, Newark, Delaware

The I-95/SR 896 Interchange is a major interstate exit for the city of Newark, Delaware and is located approximately 2.5 miles from the Delaware/Maryland state line. Major congestion frequently occurs at the interchange as well as on I-95 and SR 896 during peak rush hours and other times due to both commuter and pass-thru traffic on the heavily traveled I-95 interstate corridor. The frequency of these traffic problems has increased over a prolonged period of time. Traffic safety is another major issue at this particular exit. The I-95/SR...

Eidenau Bridge Replacement, T-325 over Breakneck Creek

This project involved replacement of the existing bridge carrying T-325 Textor School Road over Breakneck Creek with a 70’ single span, composite pre-stressed, bulb-tee beam bridge on integral abutment foundations supported by H-piles bearing on bedrock.

The structure was widened to the north in order to accommodate two travel lanes. The project also included vertical and horizontal realignment of the existing...

E02313 General Designer Open End, WO #2 — SR 519 Roundabouts Final Design

For the final design of two multi-lane roundabouts on SR 519 services were provided as part of an open-ended engineering services contract. The roundabouts are located approximately 400’ apart at the intersections with SR 1055 northbound and SR 1055 southbound. While this innovative design was set to improve traffic flow and relieve congestion at these intersections, it has also left the smallest project footprint on the topography of the area. The following services were provided for the project: Project Management/Project Administration....
