Orangethorpe Avenue Closure

As part of the OC Bridges Project, Orangethorpe Avenue will be closed to through traffic between Thames Street and Chapman Avenue.

Drivers can use either Kraemer Boulevard to the west or Tustin Avenue/Rose Drive to the east, with Alta Vista Street to the north and Miraloma Avenue to the south.

The project includes relocation of underground and overhead utilites; construction of temporary sound blanket walls and retaining walls; building of a new Orangethorpe Overpass bridge; improvements to the Atwood Channel; and building a new Miller Street roadway bridge.

Construction is expected to be completed by spring, 2016.

Project Summary

The Orange County Transportation Authority (OCTA) is building a series of bridges to separate trains from vehicles along the Burlington Northern Santa Fe (BNSF) corridor in Fullerton, Placentia and Anaheim. In accordance with federal railroad safety regulations, residents should expect to hear an increase in the frequency of train horns because of construction activities on and around the railroad tracks, regardless of quiet zone designation. Funding sources for the OC Bridges Project include Measure M, Orange County's half-cent sales tax for transportation improvements, and California Proposition 1B Trade Corridor Improvement Funds.

Lakeview Avenue Bridge Project
