The proposed State Route 239 Project would provide a new, four-lane highway from State Route 4 at Marsh Creek Road in Contra Costa County to Interstate 580 in Alameda County or Interstate 205 in San Joaquin County. This new state route would ultimately improve the transportation network for an area that has few viable north-south roadway connections in this approximately 17-mile [emphasis added] stretch between eastern Contra Costa and the Central Valley.
Caltrans is trying to sneak this one past, but hawk-eyed advocates aren't having it, as seen in the tweet below from Bike East Bay's Robert Prinz:
Since Caltrans isn't providing the meeting link in advance & nor a meeting registration/reminder option, I'll do it myself. Enter your info via the form below & I'll email you with a reminder & the meeting link on December 13 as soon as it's posted.https://t.co/31DH0SXK8B
