History
Although segments of Route 4 had been part of the state highway system since 1909, Route 4 was officially designated as such between US Route 40 (now Interstate 80) and State Route 99 in 1934. Prior to that date, the then-existing segment was officially known as the "Borden Highway", and the bridge over the San Joaquin River is still referred to as the "Borden Highway Bridge" in tidal tables. Construction of Route 4 did not finish until 1935, however.[2]
The portion of Route 4 from US Route 40 to State Route 24 was added to the highway system in 1933 as Legislative Route Number (LRN) 106. East of the concurrency with State Route 24 to State Route 49, Route 4 was designated as LRN 75 from 1931 to 1934. Finally, the segment from State Route 49 to State Route 89 was signed as LRN 24 from 1909 to 1934.[2]
In the 1970s, a significant portion of the
From 1998 to 2009, a road built by the State Route 4 Bypass Authority, named the State Route 4 Bypass, opened in three phases, bypassing Route 4 in Oakley and Brentwood to the south and west.[19][20] Many of the signs and local maps designated this extension as simply "Bypass Road". A section of Marsh Creek Road was widened to serve as the connection between the bypass built by the authority and the original Route 4 towards Stockton. In 2012, Caltrans handed over authority for State Route 4 in Oakley and Brentwood to the respective cities. In return, it gained control of the bypass and the upgraded section of Marsh Creek Road, which officially became State Route 4.[21]
In 2004 voters passed a half cent tax increase to fund widening from 4 to 8 lanes from Loveridge Road to Hwy 160. The project lasted from 2010 to 2016 through Pittsburg and Antioch, with the final configuration as three mixed use lanes and one High Occupancy Vehicle (HOV) lane in each direction and auxiliary lanes between interchanges as far as the interchange with Route 160. The median accommodates the eBART extension of the Bay Area Rapid Transit (BART) system.[22] In early March 2016, reconfiguration of the interchange of SR 4 and SR 160 was officially opened, allowing westbound SR 4 traffic to access northbound SR 160 directly and southbound SR 160 to access eastbound SR 4.[23]
From SR 160 to the Balfour Road interchange it continues as a multi-lane freeway. In 2011, Caltrans awarded $25 million toward upgrading the section from Lone Tree Way to Sand Creek Road to a full freeway and constructing an interchange at Sand Creek Road. Sand Creek interchange opened in 2015 and Balfour Road in 2018. [24] [25] The portion from Balfour Road to Vasco Road is single-lane each way and has a signal-controlled grade crossing at Marsh Creek Road.
The freeway segment of SR 4 in Stockton is part of a proposed route to upgrade SR 99 into
In 2016, Pittsburg moved to install surveillance cameras along their portion of the route, in response to a series of 20 freeway shootings in the area that had taken the lives of six people, and injured 11, in the past year.[27]
Major intersections
Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary ( ).[28] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.

SR-4/I-680 interchange improvements
On February 1, 2019, the Brentwood Press newspaper reported that officials representing the Contra Costa Transportation Authority (CCTA) and the California Department of Transportation (Caltrans) had held a groundbreaking ceremony to start a project that is intended to reduce congestion at the SR 4/I-680 interchange just outside Martinez. The multiphase project will widen SR 4 by adding a third lane in each direction, beginning at Morello Avenue in Martinez and ending at the merge of SR 4 and SR 242.[a] It will also include replacing the 50-year-old Grayson Creek Bridge, which has outlived its serviceable life and does not meet current bridge safety codes. The project will impact about 4 miles (6.4 km) of SR 4. Although no schedule or end date has been announced, the officials said that the estimated cost is about $136 million (in 2018 dollars).[36]

Interstate designation, under the current proposal, would apply to the 260-mile (420 km) segment between the junction of State Route 99 with I-5 south of Bakersfield to I-5 in Stockton using State Route 4 as the connector to I-5. Since there is an I-99 route currently in existence in Pennsylvania, it is anticipated that should designation be granted, the Route 99 designation would become either I-7 or I-9 to satisfy Interstate numbering convention.
