General Road and Highway Discussion

If they close the Lancaster ramps (or even if they don’t, actually) they should remove the ramp for taking eastbound Bridgeport traffic onto the freeway. Instead, have everybody turn left and use the same ramp as westbound traffic. That would simplify traffic flow on the expressway. While they’re at it, have that lane not merge; instead it can simply become the 3rd lane ahead of the 4 lane section.

Adding a left turn there onto the freeway doesn't seem better to me. Is it just to improve merging on the freeway? If so I think you'd have better options - particularly if the Lancaster exit is closed. You could do things like extending the eastbound-bridgeport on ramp into where the current Lancaster exit is adding more space between merge areas or you could have the eastbound-bridge port traffic merge into the westbound-bridge traffic on-ramp and then ultimately into the freeway. Both of these seem fine if you're not rushed to close the lanes because of the Lancaster exit.

I'm not sure you'd be able to do 3 lanes under the Lancaster street bridge. But if you could I'd say extend the westbound-bridgeport on ramp to be the 3rd lane (no merge required) and then have a normal merge from the eastbound-bridge port traffic on ramp.
