The 60 Swarm Projects

Project Description

The 60 Swarm is an impressive undertaking of two projects along State Route 60 (SR-60) passing through the San Bernardino and Riverside Counties: The Pavement Rehabilitation Project and the Three Bridges Replacement Project. SR-60 is a heavily traveled east-west corridor for commuters and goods movement in Southern California.

Project Details

The $134.5 million Pavement Rehabilitation Project, which includes $16.9 million in SB-1 funding, is re-paving the main line, shoulders and the on and off-ramps for a sixteen mile stretch of SR-60 in both directions. The project passes through five cities beginning in Riverside at the 60/91/215 interchange and crossing through to Euclid Avenue in the Cities of Chino and Ontario. The pedestrian sidewalks at the end of the ramps are being upgraded to ADA standards and new metering fixtures will be installed at the end of the ramps.

The condition of the existing pavement is poor with a high percentage of third-stage cracks and corner cracks in the two outside lanes, including damaged pavement in various location in other lanes of traffic.  The continued deterioration of pavement severely decreases the ride quality of existing roadway and potentially adversely impact goods movement and the motoring public.

The $23 million Three Bridges Replacement Project, which includes $10.4 million in SB-1 funding, will repair deteriorated slabs and replace three bridges along SR-60 for improved structure safety and increased vertical clearance.  The bridges include: Pipeline Avenue, Monte Vista Avenue, and Benson Avenue.

What to Expect

A traffic reconfiguration will be in place on SR-60 from Archibald Avenue to Euclid Avenue for approximately six months to one year allowing daytime work to take place behind k-rail. Lanes will be available in each direction on SR-60 during the day with most of the work being executed in the overnight hours. Lane excavation during the Pavement Rehabilitation Project will cause temporary minor vibrations and noise during construction.

The Three Bridges Project will have occasional full directional closures for demolition of the bridges. Only one-side of the bridges will be demolished at a time, leaving the other half of the bridges open for two-way traffic.

Motorists are advised to use State Route 91 (SR-91) and Interstate 10 (I-10) around the 60 Swarm as alternate routes to avoid delays. Local businesses are open during the project. The speed limit will be lowered to 55 miles per hour within the 60 Swarm Project limits.

Project Need

The 2008 Pavement Condition Survey Inventory (PCSI) indicates the existing pavement exhibits extensive cracking and corner breaks. The increased vertical clearance on the bridges is necessary as the route is part of the National Network for Federal Surface Transportation Assistant Act (STAA) for oversized trucks. These projects will rehabilitate the existing pavement with a roadway structure that will provide an extended service life and require less maintenance expenditures, minimize maintenance worker exposure and improve ride quality.

SR-60, an east-west corridor, is a major commute and goods movement route through a large urbanized area of Southern California.  It also serves the commercial center for Los Angeles, Orange, Riverside and San Bernardino counties, including the Ontario International Airport.

Both projects will improve traffic flow, increase safety and extend the roadway’s service life.
