Carnegie Museum to host presentation on bridge history May 12

HOUGHTON -- Kris Mattila, Michigan Tech associate professor of Civil and Environmental Engineering, will give a slide show presentation about the design and building of "the most significant civil engineering structure, exclusive of the mines, in the western Upper Peninsula" from 7 p.m. to 8:30 p.m. Thursday, May 12, at the Carnegie Museum.

Mattila, Dumpster-Diver-Extraordinaire, will explain how, in 1959, the piers were built underwater using the caisson method; how the lift span, built just west of the bridge on the shores of Hancock, was floated into position with only eight inches leeway; what it means to be the last bridge to be "field riveted"; and how a serendipitous dumpster-dive behind Dillman Hall helped to preserve this history.

The Carnegie Museum is on the corner of Huron and Montezuma Streets in historic downtown Houghton. Parking is available behind the building or in the City lot across Montezuma Street.
