In the winter of 1913, the Seattle-based hydraulic contracting firm Lewis, Wiley & Morse began work on a regrade, fill and seawall project along Alki Avenue in West Seattle. The construction continued through 1913 and was completed in the spring of 1914. The project involved a hydraulic hillside regrade near the intersection of Fairmount Avenue and Alki Avenue. A new seawall was constructed along Elliott Bay and a municipal water system pipeline installed along Alki Avenue. The existing wood plank roadbed was also widened during the 1913-1914 projects. Alki Avenue was eventually paved in 1923. Between 1902 and 1917, three bridges were built to serve West Seattle, though none of these were permanent structures. This photo shows the western approach of one of the early wooden bridges near Spokane Street under construction. The new grade on Alki Avenue (now Harbor Avenue SW) can be seen here, with the bank to the right showing the original level.
