Bridge Plans

Selections from the plans for Bridge 9340 from the files of the Minnesota Dept. of Transportation, Bridge Division:

The plans document the construction (1964-1965) and repair (1977) of Minneapolis' Bridge No. 9340 (the I-35W bridge).

Another set of plans document the construction (1962-1965) and repair (1974-1975) of Saint Paul's Bridge No. 9800 (the Lafayette Road bridge).

Both sets of plans show various aspects of the bridges' construction, including piers, elevations, abutments, scales, drainage, decks, structural steel framing, splices, electrical, railings, expansion joints, trusses, spans, and bearings.

An inventory of both sets of plans is available online or in the MHS Library.
