Annual Slab Replacement To Begin Late July

In response to resident input, the City’s elected officials have continued to focus their attention on the annual street maintenance program. The City annually reviews all City streets and develops a cost-efficient schedule to replace deteriorated concrete slabs based on the condition of each slab. To equitably select these slabs, City staff perform field inspections and use GPS equipment to identify the street segments that are in the worst overall condition within the City. This information is processed by the engineering staff to cost-effectively prepare the annual slab replacement program.

Residents are encouraged to use alternative routes around the construction zone whenever possible. Extra attention to changing road conditions is greatly appreciated. For more information, please visit www.wentzvillemo.gov/SlabReplacement.
