This photo is from a phased construction bridge replacement on I-75 near Findlay, OH. The project consisted of adding 2 lanes of traffic (going from 4 lanes to 6 lanes) to the existing interstate corridor. Rather than widening the existing bridges from 2 lanes each to 3 the DOT option to replace them with a buried bridge. The buried bridge consisted of a 48' span x 21.1' rise deep corrugated structural plate structure. It was partially assembled adjacent to the bridges and then pulled into place beneath them. The structure was backfilled with the existing bridges in place. When the backfill reached the point where it was not possible to compact it, the existing bridges were removed to complete the fill. The bridge piers were left in place. Lanes were shifted above the structure as the road was widened, eliminating the need for a detour.

This is a picture of the VT Route 2B bridge crossing over the Lamoille Valley Rail Trail in St Johnsbury, VT. This buried bridge was constructed to replace a 3 span steel bridge constructed in the 1930s and had to be sized to accommodate possible future restoration of the pedestrian trail back to rail traffic as is so often the case for these types of projects. The structure has a span of 47.9 ft and rise of 26.8 ft. The existing bridge was a local landmark, so the community wanted to make sure the replacement structure was visually appealing. This was accomplished with the use of mechanically stabilized earth (MSE) walls with colored concrete and incorporation of a decorative concrete railing to resemble the railing for the old bridge. The structure was build using precast concrete footings and an accelerated schedule to minimize the time required for a convoluted detour due to the undulating topography of the area. The project was completed ahead of schedule.

This is a 6x2 structural plate vertical ellipse carrying Lamoille Valley Rail Trail below I-91 near St Johnsbury, VT. I found this while working on a buried bridge structure about half a mile away on the same trail. This structure was built in the 1960's when the the trail was built on an old rail bed. The structure has no signs of deterioration inside or out - in spite of being located below an interstate in the northern US and being subjected to deicing salts every winter. All indications are that this structure should be able to easily achieve a 100+ year service life.

This is the inside view of one structure of twin deep corrugated structural plate 39.7' span buried bridges in Laguna Niguel, CA. The structures were built to replace a low water crossing into a community park that was frequently flooded. The buried bridges eliminated the flooding issue and also provided a signature entrance to the park. This picture was taken inside one of the structures and shows the clean lines and consistent quality of the deep corrugated plates as they are traced along the perimeter of the structure.
