OC Bridges Project
At the October 18, 2011 City Council Meeting, OCTA provided the City Council and the community with a presentation on the upcoming OC Bridges Project. In particular, the construction activities during the first six months, construction impacts including the train whistles through active construction areas, traffic impacts, detour information, and business and community outreach.

The five remaining grade crossings will be constructed over a five-year period ending with Lakeview Avenue which is scheduled to be completed in 2016.

Placentia Avenue Road Closure and Detour Map
Beginning on Monday, January 6, 2014, Placentia Avenue, between Fender Avenue and Kimberly Avenue will be fully closed to through traffic for approximately sixty (60) days to allow for the construction of retaining walls and paving of the new roadway under the bridge. This closure will result in a detour route along the project area. For a map of the route, click here. Please exercise caution while driving near the construction area. When the roadway is open, drivers and pedestrians will be able to travel on Placentia Avenue with no delays caused by railroad activity on the bridge above them.
