1937, back when this was the US 40/50 split with Route 17 coming on the north and south. From Eric Fischer's Flickr page:

Modern looking interchange given that this was from 1937
not a maze then - compared to what it is now.

Yet the fact the interchange was so uncomplicated...actually leads to some serious design problems: drivers continuing on 50 west (now 580 west to 80 west) would have to switch to the right lanes, while traffic continuing on 17 south (now 80 west to 880 south) had to do the exact opposite - in the same carriageway!

And yet even years later other DOTs are still building the same designs:

Across the Berkely Bridge northbound, I-264 comes in from the left 2 lanes and then exits the right 2 lanes, while I-464 traffic from the south comes in as the right 2 lanes and then exits the left 2 lanes (as US 460 into downtown Norfolk), so any through traffic must change lanes. Majority traffic movements conflict here, as significant traffic coming from 264 wants to stay on 264, and significant traffic coming north on I-464 from Chesapeake wants to go into downtown - there is little need for it to go east on 264.
The same situation occurs in reverse crossing the bridge southbound.

Was this part of the Bay Bridge project that was completed in the same year?
