RCI is serving as the general contractor for the replacement of an existing concrete bridge over LaCroix Creek on the 2300 block of South Sprigg Street in Cape Girardeau, Missouri. The existing bridge suffered damage in June of 2013, when large sinkholes formed adjacent to the north end of the existing bridge.  The City of Cape Girardeau and Buzzi Unicem a nearby cement plant worked to get the sinkholes filled in as it was causing flooding issues into the nearby Buzzi Unicem quarry.  As a result of the sinkhole activity, the bridge footings became unstable and the bridge suffered damage and had to be closed due to potential collapse.  This project includes removal and replacement of an existing waterline attached to the bridge, concrete street construction, sinkhole remediation and bridge demolition and replacement.

Prior to bridge demolition, RCI will install a temporary waterline across LaCroix Creek to provide a nearby Dairy Farm and the Buzzi Unicem cement factory with water during construction. Upon completion of the new bridge, the permanent waterline will be attached utilizing hangers designed specifically for this project.  As previously mentioned, this area has several potential sinkhole locations and RCI is tasked with remediation of those sites.  The project design firm determined the potential sinkhole locations by accomplishing exploratory drilling during the design phase of the project.  RCI will excavate those sites up to 25 feet deep and install concrete caps on the mouth of the potential sinkholes.  The concrete sinkhole caps include vertical large diameter High Density Polyethylene piping that is used for both monitoring sinkhole activity and grouting operations should those areas become active.

The new bridge will have four concrete support bents with concrete girders and a concrete deck that span both LaCroix Creek and the large sinkhole areas on the north end of the existing bridge. The project will be complete by August 2017 and is being jointly funded by the City of Cape Girardeau and the Missouri Department of Transportation.
