The City of McPherson street network totals 87 miles. Recognizing streets as a valuable asset, the Street Department strives to complete preventative maintenance to keep streets in optimum condition for the long term. When major projects are constructed, two to four years are required to develop project designs, secure right-of-ways and move utilities. Five factors are considered when evaluating a street. Those factors include traffic volume, what percentage of that volume is composed of trucks, the structural thickness of the roadway, subgrade strength and cost.
