Stream Mitigation Monitoring for West Perimeter Road

LJB monitored stream mitigation and created a Mitigation Monitoring Report to document the results of impacts that occurred due to a culvert extension at the Dayton International Airport, which impacted a total of 1,575 linear feet of stream. The stream mitigation has been implemented at Englewood MetroPark, a Five Rivers MetroParks property on River Road, approximately three miles west of the impact site. The enhancements included 2.7 acres of invasive species...

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...

Wright State Way Pedestrian Bridge over Interstate 675

This project constructed a new 500-foot pedestrian bridge over Interstate 675 connecting the cities of Beavercreek and Fairborn. The bridge provides safer access from Wright State and Clark State universities and adjacent properties to the retail and commercial properties on the other side of the interstate without requiring pedestrians and cyclists to use a high-volume vehicular bridge. A 3-D model was built using MicroStation to take advantage of the enhanced rendering...
