Business Loop I-10 - Colton and Fontana

This business route begins east of Interstate 15 and follows Valley Boulevard (former U.S. 70-99) through Colton between Exit 59 (Etiwanda Avenue/Valley Boulevard/Commerce Drive) and Exit 71 (Mount Vernon Avenue). The loop was signed at least once on Valley Boulevard still in 2006, but this business loop is not listed in the 1991 state signing log. Remnant signs, especially in the city of Colton, can still be found along Valley Boulevard as of 2008. Remnant signs are harder to find west of there toward Fontana. There are no signs for this business route from mainline Interstate 10.
