TRC was hired by the City to perform an analysis and alignment study, as well as prepare the Project Report and full PS&E documents, for this $26 million project which encompassed the widening of almost two miles of Plaza Drive from two lanes to four lanes. It also included widening the Plaza Drive/SR198 interchange overcrossing structure from three to seven lanes, and the addition of auxiliary lanes on both sides of SR 198 from the State Route 99 Interchange to Plaza Drive.

Plaza Drive provides access to growing commercial and industrial areas in Visalia and carries 13,800 vehicles per day, including heavy truck traffic. The objective of the project was to reduce travel time for motorists, enhance safety, and promote economic growth across Tulare County by improving access to employment centers and enhancing the movement of goods. The wider roadway and enlarged interchange will serve to alleviate traffic congestion and provide better access to Visalia’s Industrial Park which is home to many major product distribution centers serving the western United States.

TRC prepared the PS&E for all roadway design, including pavement design, structure design, and drainage design, as well as performed the right of way, utility and permit coordination, and managed subconsultants for traffic signal and landscaping design. ADA improvements were also incorporated along the entire corridor. All work products were subject to Caltrans reviews and approvals, including receipt of final encroachment permit approvals. The project was expedited and completed on time in order to secure several million dollars in available funding.
