Calhoun County Halbert Road 20’ x 5’ Snake-Shaped Box Culvert
This award winning precast concrete project is located on Halbert Road over Waubascon Creek in Bedford Township, Calhoun County, Michigan.
Delta Precast was contracted by Northern Concrete Pipe, Inc. to provide structural design, computations, load ratings and a drawing review.
In order to install the precast elements, the stream was diverted with the culvert bed dewatered. A 6-inch thick concrete sleeper slab was installed to set the culvert on.
It took three days to deliver the precast sections which were installed with a crane. The culvert was then backfilled to specifications, compacted and paved.
In February 2020, the Halbert Road culvert project won the ‘Award of Excellence’ from the Michigan Concrete Association under the structural concrete – small transportation category.
