DISCUSSION Currently, the First Street Bridge over the Santa Ana River consists of two travel lanes in each direction (Exhibit 1). This project will widen the bridge and the approaches to three lanes in each direction, along with bike lanes and with pedestrian sidewalks on both sides to make this segment of First Street consistent with the Orange County Master Plan of Arterial Highways and the City's Circulation Element. The proposed work includes demolishing the existing bridge and construction of a new, wider bridge. Other improvements include medians, trail connections to the Santa Ana River and landscaping along the approaches to the bridge. The work will be conducted in two phases. In the first phase, traffic will be directed to the south half of the bridge while the north half will be demolished and rebuilt. The second phase of the project will start immediately following completion of the first phase. Traffic in this phase will be directed to the newly completed north half of the bridge during construction of the south half. Once completed, these improvements will enhance flow of traffic, pedestrian safety and ride quality of the bridge. 23E-1
