MICROPILE FOUNDATIONS FOR RECONSTRUCTION OF HISTORIC LA LOMA BRIDGE IN PASADENA, CALIFORNIA
Casey Garneau

he historic La Loma Bridge, which crosses the Arroyo Seco in Pasadena, California, was built in 1914 to replace the 1898 California Street Bridge. The bridge is an open spandrel concrete arch bridge with a neoclassical design, which draws inspiration from Greek and Roman architectural design features with Renaissance interpretations of the classical forms. Inspired by the City Beautiful Movement, the bridge was built in response to the advent of the automobile and the increase in population in the surrounding areas. Built just a year after, the La Loma Bridge, pictured in Figure 1, displays similarities of its “big sister”, Pasadena’s famous Colorado Street Bridge, nicknamed “Suicide Bridge”, which spans the Arroyo Seco less than a mile away. While the Colorado Street bridge connected Pasadena to Los Angeles, the La Loma Bridge played a substantial part in Pasadena’s development of the west side of the Arroyo, largely called San Rafael Heights, which was annexed by the City of Pasadena by the completion of this bridge. For several years, the two bridges were the only crossings over the Lower Arroyo and represent the city’s economic and physical need to facilitate automobile traffic over the Arroyo, while also providing impressive picturesque structures for the nearby communities.
