The new Berwin Hanna Bridge on Hamner Avenue over the Santa Ana River will be 1,200-feet long and features structural, seismic and hydraulic state-of-the art design.
The newly constructed bridge will include a four-foot-wide median and shoulders along with a new, 12-foot-wide, separated multi-purpose trail on the east side of the bridge. This much-needed trail will provide pedestrians, cyclists and equestrians a safe route across the bridge and access to the regional Santa Ana River trail.
Bridge Construction
The new Mayor Berwin Hanna Bridge will be built in two phases starting with work on the west side of the existing bridge. Once complete, traffic will shift to the new west span and the existing bridge will be retired and demolished. Then work will begin on the new west bridge span.
During construction, traffic will travel on the existing two-lane bridge until the east bridge span is complete. Traffic will then move to the newly completed three-lane east span for the remainder of construction.
Traffic Impacts
Two travel lanes are expected to remain open during construction, weather and field conditions permitting. However, traffic lanes are subject to close intermittently for public safety due to contractor activities or operations.
