Project Description

The bridge replacement provided capacity increasing traffic for vehicles, bicycles, and pedestrians. Additionally, the bridge continued use of an equestrian trail undercrossing and adjacent walking path during construction. The project provided a context sensitive solution too adjacent recreational golf coarse users and the surrounding business community. Incorporated context sensitive bridge aesthetics and developed stage construction plan to ensure continued transportation link, safety & constructability. These measures lead to a Categorical Exclusion (NEPA) and Mitigated Negative Declaration (CEQA) environmental documents. Additionally, the bridge replacement project was a catalyst to water transmission line improvements that were near the design life, had a high risk of consequence of failure due to swallow depth, and required significant environmental compliance. Relocation of 32 and 36 inch water transmission lines was required to accommodate future bridge replacement (Phase II) and continued potable water service. The transmission line improvements provided sustainable infrastructure to the City of San Diego and City of Chula Vista utility owners.
