segment was constructed from the 1939 alignment to near the Merced County line, a distance of 3.26 miles. The 1934 alignment is now Dinosaur Point Road, while the 1939 and 1950 alignments continue to be in use today as part of SR 152. In 1963-65, a new 12-mile four-lane expressway, with climbing lanes for trucks, was built from the Merced County line eastward, to bypass the San Luis Reservoir which was then under construction. A three-mile stretch of the bypassed road continues to be in use as Dinosaur Point Road, providing access to a boat launch ramp at the reservoir. Between 1982 and 1992, the road was widened in two phases from two to four lanes, with some realignments, on a 10.5-mile segment from the four-lane section completed in 1950 to just east of the junction with California State Route 156. The first phase, from the 1950 segment west to Bell Station, was completed in 1984. The second phase, from Bell Station to Route 156, was constructed from 1990 to 1992, with an interchange built at Casa de Fruta. In 2008, a T-junction and stop sign at the intersection with Route 156 on the remaining two-lane section of the highway west of Casa de Fruta was replaced with a flyover, greatly easing congestion there. A segment of Route 152 west of Gilroy, between the Uvas Creek Bridge and Santa Teresa Blvd, was added to the National Register of Historic Places in 2007. This segment of the road, serving as a western gateway into Gilroy, is lined with deodar cedar trees that were planted on consecutive Arbor Days in 1930 and 1931.
