Finished Roadway – The photo shows the finished roadway over C-32-103, just prior to completion of the structure. The pictured portable, reusable cofferdams made by Dam-It Dams were used to dewater the work area while constructing finishing touches on the stoplog system. The stoplog system is the first step for WDNR Division of Fisheries in rejuvenating a deteriorating fish habitat in Wing Lake.
Culvert Replacements – Five pairs of 42 in. reinforced concrete pipe culverts were replaced, in addition to a single 72 in. concrete pipe with a 48 in. x 63 in. horizontal elliptical concrete pipe, and twin 72 in. concrete pipes with the 8 ft. x 8 ft. box culvert. The dewatering method shown in the picture was used for all of the culvert pipe end installations. A large steel plate was bolted onto the end of their trench box, and water was pumped into adjacent sediment bags before re-entering the waterway.
Slope Widening – Upon completion of culvert replacements, the contractor undertook the task of widening the slopes to accommodate the new 40 ft. wide pavement section. Seen in the picture, one of the excavators benched a section of the slope by removing existing material, and the other followed behind and placed the special 16 in. x 2 in. select crushed material. Forty-six thousand tons of rock were needed to fill the slopes of the 1.75 mile corridor.
CTH GI Facing East Completed – CTH GI looking east from the backwaters of the Mississippi. Existing slopes were widened using a 16 in. x 2 in. select crushed material, and the 24 ft. roadway was pulverized and relayed. Extra base aggregate was added to the shoulders to accommodate 40 ft. of new HMA pavement. Paved shoulders provide safety for pedestrians, bicyclists and fishermen. Tree well paths were constructed at various points along the roadway to plant new trees as mitigation for necessary tree clearing.
Completed CTH GI – CTH GI carving through the Mississippi River backwaters. This photo shows a portion of the 46,000 tons of special 16 in. x 2 in. select crushed material used to widen the slopes of the road. Numerous culverts were replaced to accommodate the newly widened roadway. Seen here is one of five pairs of 42 in. reinforced concrete pipes installed in the winter months. This also shows the tree wells that were included at the request of USACE as a mitigation piece. Trees will be planted this fall.
Landing Lot Campground – Goose Island West Boat Landing and parking lot and Goose Island Campground manager's office parking lot at Mississippi River's Wigwam Slough. The North Landing Road that can be seen heading upstream was pulverized and relayed, and was raised in two spots to help alleviate yearly inundation during flood season. Numerous park shelters, playgrounds and shore fishing spots, in addition to the north boat landing, can be accessed via this roadway.
