The La Loma Bridge, originally constructed in 1914, is undergoing a seismic retrofit and rehabilitation. The bridge will be closed for 18 months, with construction beginning in summer 2015 and the anticipated completion in winter 2016. The scope of the project involves replacement of bridge deck; rehabilitation of the arches and spandrel columns; and strengthening the end piers. The estimated cost of the project is approximately $16 million. Project funding consists of $13.3 million in federal funds and $2.7 million City funds. The La Loma Bridge Project is a collaborative effort between the City of Pasadena and the California Department of Transportation (Caltrans).
During construction traffic will be detoured to other bridges across the Arroyo Seco. Residents will be able to cross using the Colorado Boulevard Bridge to access areas north of La Loma Bridge, and will be able to use the San Rafael Bridge to access areas south of La Loma Bridge. The Department of Public Works is creating a traffic management plan to assist the flow of traffic.

About the Projects
Description

- The La Loma Bridge Project is a collaborative effort between the City of Pasadena and the California Department of Transportation (Caltrans)
- Will retrofit and rehabilitate the historic neoclassical revival design bridge that spans the Arroyo Seco
- The Historic American Engineering Record (HAER) was established in 1969 to document and save historic bridges in the United States. The documentation produced by HAER provides a permanent record of the nation’s most important historic sites and large-scale objects as well as raises awareness of bridges that require rehabilitation and restoration. The completed HAER document developed for the John K. Van De Kamp Bridge, formerly known as La Loma Bridge can be accessed here.Historic American Engineering Record (HAER) – John K Van De Kamp Bridge
Improvements
