Business Loop I-5 - Williams / Maxwell
Traveling 14.2 miles along old U.S. 99W, Business Loop I-5 connects Williams with Maxwell in Colusa County. The city of Williams is a regional agricultural center with a population of 5,123 people as of the 2010 census.
Jerry Mullady observed that Business Loop I-5 through Williams and Maxwell formerly continued northward as a seamless route with Business Loop I-5 through Willows and Orland. The California State Signing Log however indicated a subtle gap between the separate loops, so they were never officially continuous. Furthermore Joe Rouse wrote that the Caltrans signing log indicated a break in the business route north of Maxwell.
North
Business Loop I-5 branches north from a diamond interchange (Exit 575) with I-5 along Husted Road to follow old U.S. 99W (Road 99W) northwest toward Downtown Williams. Husted Road runs along the east side of the city northward to SR 20 Business (E Street).
