OCTA Grade Separation
In April 2008, the California Transportation Commission voted to approve the Orange County Transportation Authority's (OCTA) Grade Separation Program, which is currently referred to as the OC Bridges Grade Separation Program. The program includes seven grade separation projects along the Burlington Northern Santa Fe (BNSF) railroad in the cities of Anaheim, Placentia and Fullerton. The projects are partly funded through the Trade Corridor Improvement Fund, as well as various other state, federal and local sources. Among the seven crossings, four will be undercrossings and three will be overcrossings. When complete, the projects will alleviate the current and potential traffic impacts and hazards posed by existing at-grade rail crossings along the Orangethorpe corridor. The OC Bridges projects include the following improvements:
- Grade separation between the road and the BNSF railroad in seven locations
- Construction of a railroad shooflies for the undercrossing separations
- Construction of vehicular detour roads during construction
- Construction of pump stations for the undercrossing separations
- Construction of connector roads to the elevated streets for the overcrossings
- Improvements to city streets and sidewalks
- Soundwalls and landscaping along the project limits
