Some of you may find this older Highway 4 bypass article interesting. Worth noting: additional lanes largely funded by each new house built. I believe about $6,000 per Brentwood house. So by the time we get an additional lane, the population has increased so much that it doesn't improve traffic. It has never made sense to me. And the design of the road is too close to houses. There is still a stretch approaching the AMC theatre (driving from Brentwood toward Antioch) where you can literally fly off the road so be careful !! I made most of these same points at council meetings (before construction began) but it was ignored. Seems they are always in a rush, and somewhat lacking in quality thought process IMHO
