Bridge Documentation

This is one of several bridges in the city designed by A. W. Grosvenor who was known for using Melan reinforcing as he did in this bridge. The bridge originally had a brick railing, which has been replaced with a concrete railing. Despite this alteration, the bridge retains its Melan arch design and is an important historic bridge.

Information and Findings From DHPA Historic Bridge Survey

Statement of Significance

Previous Timber Structure (1864 - 1878) Gould reported that Hall & Kimball built a covered timber truss structure over St. Mary's River on W. Main Street in Fort Wayne in 1864. The structure was replaced in 1878 with an iron superstructure.

Prior Metal Structure(s) (1878 - 1921) The Allen County commissioners refused the Ft. Wayne Street Railway permission to lay double tracks on the W. Main Street Bridge in October 1893. In early November, the board received bids to move the Old or W. Main Street Bridge of one 165-foot span with an 18-foot roadway and a pair of 5-foot sidewalks to Van Buren Street over the St. Mary's River. The bridge was to be cleaned and painted with graphite paint. The county accepted the next lowest of the bids -- that of the Jackson Bridge Company of Jackson, Michigan, for $1,440. The board accepted the relocated bridge in February 1894. In January 1919, the county commissioners agreed to build a new West Main Street Bridge in the spring of 1920 to address the heavy vehicle traffic there. In July residents of the west end of Fort Wayne prepared a petition seeking the replacement of the existing iron West Main street bridge with a concrete structure. While replacement was at the top of the county's list, residents wanted immediate action to replace what they regarded as a too-narrow and too-costly structure.

Surveyed Structure (1921 - ) In the second decade of the twentieth century, A. W. Grosvenor of Fort Wayne designed about a half-dozen reinforced-concrete arched structures built in the region. In February 1920, Allen county hired Asa Grosvenor to draft plans for the Main Steet Bridge at the rate of $100 per days, not to exceed a total cost of $3,000. Grosvenor's plans were submitted to and approved by the Indiana State Highway Commission. The rings are offset, segmental, probably reinforced with the Melan system, and raised vertically upon the piers. Solid spandrel walls retain the earth fill upon which rests the asphalt roadway and 6-foot and 6-inch concrete sidewalks between stone and brick rails. The original rail panels were made of dark brick and its posts and copings of light stone. The piers are decorated and their towers inlaid with brick and stone. Herman W. Tapp of Fort Wayne beat out I. E. Smith of Richmond for the construction contract of $151,000 in May. Tapp was paid in installments, the final one coming in October. Like a number of Grosvenor's structures, this one was unusually well decorated using a variety of materials. The structure is also noteworthy for its skew. The 1997 reconstruction of the deck replaced the parapet rails with heavy coped and open-arch panelled ones.
