Replacing an existing freeway overcrossing, one of the oldest interchanges on SR 99, while accommodating local and freeway traffic throughout construction is no small feat. Yet that’s just what Nolte did. By widening the two-lane structure to accommodate eight lanes, the new Grant Line Road interchange yielded improved traffic circulation and motorist safety on the highway and along the arterial roads. The project also included six new on/off ramps, four new signalized intersections, and realignment of local roadways to accommodate the new interchange.
The project was named Interchange Project of the Year, by the California Transportation Foundation, earning a TRANNY Award in recognition of excellence in transportation.
