Originally determined eligible in the Caltrans 1985 Historic Concrete Arch Bridges in California Thematic Resources study; its continued eligibility was confirmed in the 2004 Caltrans Historic Bridge Inventory update: Concrete Arch Bridges.
Ulatis Creek Bridge (23C0018) is a two-lane reinforced-concrete, earth-filled, parabolic-arch bridge with a single arch span. It features reinforced-concrete baluster railings with massive cylinder-shaped end posts with rounded tops and a smooth finish. The fine groove texturing was cast into concrete by using specially milled lumber, similar to the trim on Vacaville's Town Hall. Using lumber to simulate the machine tooled finish called 'plucker finish' was a technique used on high quality masonry buildings of that era. Alterations include the addition of modern lanterns. The bridge, which at one time was part of the Lincoln Highway, was converted to a pedestrian crossing in 2000.
