The plans I saw before (will try to search for them again) outlined a tunnel that will start after the Kalayaan flyover, go under Paseo and Makati Ave, and come up around the Chevron building.
The most affected will be those coming from the Kalayaan flyover turning left to Paseo. Ngayon pa nga lang abot na hanggang BGC ang pila during rush hours.
