State Route 242 / Clayton Road Ramps
State Route 242 (SR242) is a 3.4-mile long connector freeway that links I-680 to State Route 4. In addition, the SR242 corridor serves commercial, light industrial and residential land uses in the City of Concord. The interchanges at Clayton Road and Concord Avenue are considered the primary access points for the Central Business District and experience heavy traffic volumes during weekday peak periods, resulting in delays and congestion that affect freeway, interchange and local street operations. The Clayton Road interchange does not currently include a southbound SR242 off-ramp or a northbound SR242 on-ramp. Since 2000, completion of the Clayton Road interchange has been a high priority project for the City of Concord to better serve the Central Business district.
