  • La Loma Bridge Project


    The La Loma Bridge, originally constructed in 1914, will soon undergo a seismic retrofit and rehabilitation.  The bridge will be closed for 18 months, with construction beginning in spring 2015 and the anticipated completion in fall 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.  A community meeting providing more information on the La Loma Bridge Project will be held in winter 2015 prior to the start of construction.
