The land use designations at and near the Project site are Rural Residential and Suburban Residential as defined by the Orange County General Plan.
Orange County Public Works, in cooperation with the California Department of Transportation (Caltrans), is proposing to replace the Modjeska Bridge (Bridge No. 55C-0172) over Santiago Creek. The Modjeska Bridge is located in Modjeska Canyon near the Cleveland National Forest. The existing bridge is a single span and crosses over Santiago Creek. The Project will replace the existing substandard steel bridge; a portion of the construction funding is provided by the Highway Bridge Program (HBP).
The proposed replacement structure is a 65’-2” long and 43’-10” wide single span prestressed, precast concrete I girder bridge. The bridge will be raised approximately one foot to increase hydraulic conveyance. Tall abutment walls, similar to the existing condition, will be set on spread footing foundations. Tall wing walls will be required at all corners. The replacement bridge will have 12-foot-wide lanes and will include 8-foot minimum width shoulders. Bridge barriers will be deck mounted concrete barrier Type 836.
