Interstate 15NB Sierra Ave Weekend On Ramp and Lane Closure

By Staff Reports

(Victor Valley)– Weekend on/off ramp and lane closures have begun on the 9-mile pavement rehabilitation project on Interstate 15 (I-15) from the 7th Street undercrossing in the City of Rancho Cucamonga to the Sierra Avenue undercrossing (UC) in the City of Fontana.  The project was awarded to Griffith/Coffman Joint Venture, Inc. for approximately $83 million on February 16, 2012.  The work includes rehabilitation of the No. 3 and No. 4 lanes in both directions, rehabilitation of the outside shoulder and widening of the inside shoulder. The work is expected to improve ride quality, extend pavement life, improve facility operation, and safety.

The weekend on/off ramp and lane closures will begin Friday night (late) and continue until Monday morning (early).  Weekend lane closures are expected to end in April 2013.  At least one lane will be open at all times during the weekend closures.  Please use alternate routes and expect delays while traveling through the construction zone.  The contractor has implemented a bypass lane that begins after 4th Street and continues for approximately 5 miles to Sierra Avenue.  The bypass lane is continuous with no exits once motorists enter
