Heads up commuters, Caltrans is planning a major rebuild of the MacArthur Maze that may require parts of the heavily traveled East Bay interchange to be shut down for months, with some traffic rerouted onto surface streets.

“It’s pretty big, probably running a close second to the building of the eastern span of the Bay Bridge,” said Caltrans spokeswoman Chiconda Davis.

... At issue are the vertical clearance heights on several of the Maze’s connectors.

Caltrans’ guidelines, adopted way back in the 1960s, call for a vertical clearance on bridges of at least 16 feet, 6 inches. The Maze’s connectors fall 1 to 2 feet short.

... The work is expected to begin in April 2022 and take 10 to 36 months, with estimated intermittent road closures ranging from three months to 15 months.

What is the official status of the entire scope of the Bay Bridge project? From I see there is some work left to demo the old piers of the bridge and the bike trail... is that it? It's hard to believe work would still be ongoing with that.

This project will modernize this interchange complimenting the new bay bridge. I'm going to hope they choose alt. c and it's hard to say there isn't money with an extra 5 billion a year for Caltrans. It would be nice to see shoulders added on the ramps.
