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.

Elements to be constructed during Phase II include the northbound High Viaduct, northbound Battery Tunnel, two Main Post Tunnels, and the Low Viaduct and Girard Road interchange. See the project overview fact sheet for more information.
