Hanley Road Water Main Replacement

The City of Clayton wants you to be aware of an upcoming project that may impact you when you travel on Hanley Road, between Clayton Road and Forsyth Boulevard. Beginning this Monday, Nov. 3, Missouri American Water Company contractors will be excavating a trench down the middle of Hanley into which a new 8” water main will be installed. The new pipe will replace a 100-year-old, break-plagued water line.

As regular drivers on this particular stretch of Hanley know, water main breaks routinely require Missouri American Water repair crews to close lanes of traffic in order to repair pipes. According to St. Louis County’s Department of Highways and Traffic, this imperative project will eliminate the chronic problem.

We want residents to be aware that this project will likely cause commute issues, with work beginning at Forsyth and advancing south to Clayton Road. The project will take at least five months, and as many as seven months to complete.

We have also been advised that lane closures, which will inevitably create congestion, will be limited to non-rush hour periods when possible. Missouri American Water’s contractor will keep both “through” lanes on northbound Hanley open until 9 a.m. on weekdays – because “north” is the dominant direction of morning traffic flow during the work week. In the afternoons, both southbound “through” lanes will be open after 3:30 p.m. – again, to accommodate the dominant pattern of traffic on the road at that time.

All five of Hanley Road’s lanes – two northbound lanes, two southbound lanes and a shared center left turn lane - will be fully reopened to traffic at the end of each work day.
