The '''Ada Covered Bridge''' is a {{convert|125|ft|m|
== Design ==
The bridge uses the Brown truss system, consisting of diagonal compression beams and almost vertical [[tension member]]s (slanting in at the top toward the center of the span)
The bridge is {{convert|125|ft|m}} long, and originally rested on wooden pilings. As is typical for covered bridges, its gabled roof is covered with creosote shingles.
Line 56 ⟶ 55:
In 1941 the Kent County Road Commission and the [[Works Progress Administration]] made extensive restorations, re-roofing the bridge with new protective creosote shingles and replacing many of its decayed underlying supports with new beams. The Road Commission purchased a nearby barn to supply wood for replacement of badly deteriorated elements.<ref>synthesised from [http://www.wmta.org/coveredbridges/ada_bridge.html wmta.org] {{webarchive |url=https://web.archive.org/web/20060508205329/http://www.wmta.org/coveredbridges/ada_bridge.html |date=May 8, 2006 }} and [http://www.relocate-america.com/states/mi/cities/ada.htm Ada page] {{webarchive |url=https://web.archive.org/web/20061024002542/http://www.relocate-america.com/states/mi/cities/ada.htm |date=October 24, 2006 }} on relocate-america.com site, accessed October 09, 2006</ref>
The bridge was listed with the Michigan State Register on May 9, 1969, and with the National Register on February 16, 1970. It was awarded a Michigan Historical Marker (site L0075) on August 28, 1974.<ref>marker data from
In 1979 the roof collapsed due to heavy snow, and the bridge was restored using funds raised by private donations. Shortly after the repairs were finished, the bridge was completely destroyed by fire. The citizens again rallied, this time with the help of the [[Amway|Amway corporation]], headquartered in Ada, and rebuilt it once again. The replica bridge, now resting on concrete abutments, is {{convert|14|ft|m}} wide and {{convert|125|ft|m}} long.
