U.S. Route 40 West Broad Street Corridor Improvements

This project included multiple studies, innovative drainage treatment, and roadway and traffic signal design that incorporated complete street concepts. The safety study entailed a thorough crash analysis identifying and plotting more than 1,200 crashes that occurred over a three-year period on the corridor. Based on the results of the initial accident analysis, LJB developed numerous countermeasures to provide short-term and long-term improvements to the safety and operation of the corridor. The design...

U.S. Route 68 (Detroit Street), U.S. Route 42 (West Main Street), and West Main Street Safety and Pedestrian Improvements

The lack of dedicated bicycle infrastructure and way-finding signage for cyclists on Detroit Street created a break in an otherwise well-connected trail system. LJB initially performed a traffic safety study of the corridor to evaluate existing safety performance and develop typical sections to enhance multimodal travel. As a result of the study, a road diet treatment was recommended and designed to address identified safety deficiencies and to create a more balanced...

State Route 799 Conventional and Composite Bridge Replacements

For this unique pilot project, LJB designed the replacement of two prestressed concrete box beam bridges. The purpose of the project was to compare the long-term sustainability of using different types of construction materials. One of the bridges was designed using conventional materials, while the other bridge uses long-lasting carbon fiber composite cable (CFCC - Tokyo Rope) strands and stainless steel bar reinforcing in the superstructure. Both bridges were replaced...
