Construction of the Presidio Parkway was planned in two major phases in order to:
- Receive federal stimulus funding and begin construction sooner;
- Achieve seismic safety faster by switching traffic off of Doyle Drive and onto the completed Phase I structures (completed in April 2012);
- And shorten the total length of construction from the original schedule.

On April 30, 2012, seismic safety was achieved on Doyle Drive. Traffic now travels on a temporary bypass comprised of the completed southbound High Viaduct, completed southbound Battery Tunnel, and a temporary bypass. This roadway will carry traffic until the project is complete.
