Here's an announcement provided by the :
The newly constructed Portola Avenue Overpass will be fully open to traffic beginning Wednesday, March 21, earlier than originally scheduled.
The contractor is finishing up the striping operation today and plans to have the lanes open to travel tomorrow afternoon, which is well ahead of the original schedule. Electronic message boards will be placed at the junction of Portola and Airway to advise motorists of the new route to I-580.
The opening of the Portola Avenue overpass is the final step of the Isabel/I-580 Interchange project.
About the opening, Livermore Mayor John Marchand stated:
“I am pleased to see this final component of the Isabel Interchange project opening early. The Portola Overpass benefits all of Livermore by providing greatly improved access to the residences, and businesses on the north side of I-580 and to Las Positas College. The incorporation of bicycle and pedestrian friendly features into this crossing enhances the use of non-motorized transportation resulting in a cleaner and more healthy environment for the City.”
