Traffic is shifted to the opposite side of the road in the design so that left turns can be made onto the highway without having to cross oncoming lanes. The cost of this project was $25 million and cost less than a traditional cloverleaf design. There are also median paths for cyclists and pedestrians protected from vehicle traffic.
Flyer printing can be used to provide more details about such updates and their benefits for drivers, pedestrians, and cyclists.
The interchange site engineer and manager for Solano County, John Adams, said this many be unconventional for drivers, but traffic will not be crisscrossing at the same time with this design. Solano Transportation Authority’s projects director, Nick Burton, noted:
“..by allowing drivers to enter westbound Highway 37 from the left side of the road, the design eliminates the need for two separate traffic lights.”
He said that this crisscross design also saved an estimated $75 million as opposed to a standard cloverleaf interchange.
This project is also the first phase of an effort to widen and elevate Highway 37 from Vallejo to Highway 101 in Marin County.
