As a subconsultant, Hardesty & Hanover is providing structural, civil, traffic, and geotechnical engineering; safety inspection; bridge deck evaluation; and survey services for the Route 195 Southbound Lanes project. The team’s approach is to focus on long-term durability and low maintenance options, incorporating the most cost-efficient and feasible design solutions.
The southbound Downtown Expressway (Rt 195) over Powhite Pkwy (Rt 76), the CSX Railroad tracks, and Ramp S was constructed in 1975 and has exceeded its design life. The bridge is located on a busy, urban, high-speed interstate carrying more than 85,000 motorists per day.
The bridge has two column piers and steel pier caps, which makes maintenance-of-traffic and staged construction particularly challenging. To minimize potential traffic impacts, Synchro modeling and analyses will be used to determine the most feasible and effective sequence-of-construction and transportation management plans.
