Colton is the site ofColton Crossing, which was one of the busiest at-graderailroad crossings in the United States. The crossing was installed in 1882 by theCalifornia Southern Railroad to cross theSouthern Pacific Railroad tracks while building northward fromSan Diego. As a result of railroad acquisitions and mergers, this became the point at which the Burlington Northern Santa Fe's "Southern Transcontinental Route" crossed the Union Pacific's "Sunset Route". As traffic on each line began to soar in the mid-1990s, fueled largely by the vast increase in imports passing through the ports ofLos Angeles andLong Beach, the primitive crossing became a seriousbottleneck. On August 28, 2013, the at-grade crossing was officially replaced by a fly-over that raises the east–west UP tracks over the north–south BNSF tracks.
Despite its status as a railroad town, Colton does not have passenger rail service. Passenger trains operated byAmtrak andMetrolink pass through Colton but do not stop there.
Before Spanish settlement, the area was inhabited by theTongva,Serrano, and Cahuilla.[4][5] The Tongva village ofHomhoangna was located in the area that is now Colton, situated near the base of the foothills ofReche Canyon, historically known as Homhoa Canyon, derived from theTongva language wordhomhoabit or "hilly place."[5]
During the Mission Era theMission San Gabriel established a Spanish settlementPolitana in 1810, just northeast of what is now Colton.[6] By 1840, Colton was part of two private ranchos, Jurupa and San Bernardino Rancho.[4] From southwest area of modern-day Colton was known as "Agua Mansa" (Gentle Waters). It had been settled by New Mexico pioneers in 1842.[4] What is currently known as Cooley Ranch was known as Indian Knolls for nearly 100 years. This is because the Indians living in what is now the San Bernardino Valley found refuge on the knolls of the property during theflood of 1862.[4]
The original owner of the property was George Cooley ofKent, England who had moved to Colton in 1853 and who purchased 200 acres at $3.50 an acre along theSanta Ana River the next year.[4] Cooley was chairman of the San Bernardino County Board of Supervisors inSan Bernardino County.[4] By 1873, the property had mushroomed into a 400-acre property. Eventually, when property taxes had increased, the property was sold to Villelli Enterprises ofLa Habra.[4] The city was named afterDavid Douty Colton, who had been abrigadier general of theCalifornia State Militia in 1855, prior to theCivil War.[7] He was later the vice president of theSouthern Pacific Railroad Company.[4]
Virgil Earp lived in Colton at 528 West "H" Street[8] where he was the town's first marshal.[9] He resided in Colton from 1883 to 1889.Morgan Earp is buried at Hermosa Cemetery.
In 1953, a significant portion of the historic downtown of Colton was bulldozed to make room for the Ramona Freeway, which would later be named theSan Bernardino Freeway. This included the block on the west side of Eighth Street north of J, including the then 70-year-old Helman's Department Store building, originally housing the First National Bank of Colton, on the corner and theWillet's Department Store building to its north. Both stores moved to locations further north on Eighth.[10]
