OC Bridges Project

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.

Orangethorpe Avenue Closure

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

Lakeview Avenue Bridge Project

OCTA is moving forward with the construction of the Lakeview Avenue overcrossing, which will reconstruct Lakeview Avneue as a bridge to allow vehicles to pass over the Burlington Northern Santa Fe Railway tracks. The overpass will be built at Lakewood Avenue and the Burlington Northern Santa Fe Railway between Orachard Drive to the norht and Eisenhower Circle to the south. When completed, the project will move cars safely and smoothly over the railroad tracks, enhancing safety and boosting mobility.

Open House for Lakeview Avenue

OCTA will be hosting an Open House to learn about what to expect during the construction of the Lakeview Avenue Overcrossing on:

Placentia Yorba Linda Unified School District

Orangethorpe and Tustin Avenue/Rose Drive Bridge Project
OCTA has begun construction of the Orangethorpe and Tustin Avenue/Rose Drive (Tustin/Rose) overpass, along the Burlington Northern Santa Fe Railway. Approximately 2,100 feet of Tustin/Rose will be elevated and realigned to pass over Orangethorpe Avenue and the railroad tracks.

Orangethorpe Avenue Road Closure

The Orange County Transportation Authority (OCTA) previously planned for the construction of the bridge to be built while Orangethorpe remained open via a bypass road. However, due to the complexity of utility relocations by AT&T, Edison, and the Gas Company, full closure of Orangethorpe Avenue will be necessary in order to remain on schedule. Starting August 11, 2014 Orangethorpe Avenue will be closed to through traffic from Thames Street to Chapman Avenue. Portable changeable message signs will be engaged at key points for a minimum of ten days before the road closure. Please exercise caution while driving near the construction area. When the roadway construction is complete, drivers and pedestrians will be able to travel on Orangethorpe Avenue with no delays caused by railroad activity on the bridge below them.
