This project consisted of 1.1 miles of concrete freeway reconstruction, ramp reconstruction, freeway lighting, traffic signal upgrading, anti-icing and intelligent transportation system installations. As well as six structure replacements (the S-Curve), structure rehabilitation and intermittent retaining wall construction on US-131 from South of Wealthy Street Northerly to North of Pearl Street, in the City of Grand Rapids, Kent County, MI.

In addition, Driesenga & Associates, Inc. supplied contractor staking which included bridge footing and wall layouts, pier layout, slope staking, pavement layout, utility layout and as built topographic surveys.
