South Gulph Road expands to two lanes each direction at the intersection with Trinity Lane / 476 ramp. Many drivers assume normal "keep right" rules and get in the right-hand lanes, but those end a couple of hundred feet on the other side of the intersection. Drivers have very little warning that they need to squeeze over which causes a lot of close calls.

If the intersection can't be redesigned, there should at least be better signage on each side, plus those big reflective sideways arrows on the road itself to warn drivers their lane is about to disappear.
