Street Design

Main Street Improvement Plan; City of Carson, California

Main StreetRKA Consulting Group provided professional engineering services for the Main Street Improvement Plan Project in the City of Carson, California.  The project involved the design, construction administration, and construction management of approximately 1.5 miles of street reconstruction.  Main Street is a major arterial through the City of Carson, which services several large businesses throughout the day and evening hours.  The new street design included full street reconstruction, median installation, and parkway improvements.  A major challenge that was encountered during construction was the uncovering of the original P.C.C. pavement along the center of the street (approximately 20’ wide).  Previous pavement rehabilitation projects did not remove the existing concrete and investigations for this project did not identify it.  Design modifications had to be made during the construction to accommodate the unforeseen conditions and were done so with minimal impact to the project.
