Description
The Santa Inez Avenue Bridge (35C0090) was built in 1903 and features rolled-steel beam side spans over sidewalks with steel bents and reinforced-concrete cantilevered abutments, and a dry-laid random-ashlar masonry retaining wall. The bridge is one of four underpasses in San Mateo situated on the former Southern Pacific Railroad route between San Francisco and San Jose which are eligible for the National Register under Criterion A for their association with the development of northern San Mateo and with the growth of grade-separation construction during the early twentieth century and under Criterion C as representative of features once common to railroad underpasses that are illustrative of an important phase of development in the evolution of underpass design. Southern Pacific built the Santa Inez Avenue Bridge during the company's phase of upgrades and development during the early twentieth century. The period of significance is 1903.
