la loma bridge imageUnder this alternative, the existing La Loma Bridge would be repaired to meet current State and Federal design standards.  A detailed seismic analysis will be done to determine the required retrofit schemes.  The preliminary seismic analysis indicated that the existing arch ribs and columns must be strengthened in order to resist seismic loads and prevent the bridge from collapsing.  The repairs would also include widening the bridge two feet on each side to meet American Association of State Highway and Transportation Officials (AASHTO) requirements, improve other safety features such as bridge railings and approach guardrails, and preserve the historic elements of the bridge that contribute to the bridge's overall appearance.

The estimated cost of this alternative is $11.5 million.
