CDFW has executed Streambed Alteration Agreement no. 1600-2017-0105-R6, pursuant to section 1602 of the fish and game code to the project applicant, the city of Beaumont. The project is limited to the phased construction of a new interchange at SR 60 and Potrero Blvd. Phase 1 includes a new 6-lane Potrero Blvd overcrossing with a temporary connection to Western Knolls Avenue. Phase 2 includes westbound and eastbound diagonal and loop entry ramps (two lanes plus HOV lane); extended ramp acceleration/deceleration lanes; realignment of Eastern Knolls Avenue; and removal of Western Knolls Avenue connections to SR 60.
