Ladue Road Project

The city closed a portion of Ladue Road east of New Ballas in both directions for repairs between June through September. The affected area ran between New Ballas Road and the entrance to Shaare Emeth.

The emergency repairs were required to stabilize Ladue Road after a failure of the hill on the south side of the road caused the shoulder to collapse. The failure showed itself with a crack in the Ladue shoulder in early May, following several days of rain.

PROJECT UPDATE (SEPTEMBER 19, 2017) Ladue Road Open

Ladue Road is now open in all directions. Crews completed repairs on September 29 and reopened the road to traffic. The project was the largest and most significant roadway repair that the city has needed to complete this year. The total cost of the project is about $819,000, all of which was funded through the city’s reserve fund that was established years ago for a roadway emergency such as this. Thanks to this fund, none of the city’s planned pavement maintenance programs were delayed due to this project. The city appreciates all who assisted with this project and is especially grateful to the community for enduring the detour over the summer.

PROJECT UPDATE (SEPTEMBER 22, 2017) Ladue Road Project

This week saw the completion of asphalt pavement repairs and further restoration of the edge of the road. 

Some site issues moved the guardrail installation and the remainder of the roadway restoration to the week of September 25. This should cause any delay in opening the road by October 1, but there may be some minor road work after the road is reopened. Ladue will remain open during any future work.

We appreciate your continued patience with this closure.

PROJECT UPDATE (September 15, 2017)Piers and new curb

During the week of September 11, crews removed and replaced the south shoulder of Ladue Road and replaced it with a concrete curb and gutter, making one more step toward the completion of the roadway restoration.

The week of September 18 will be busy on Ladue Road, as work will shift toward asphalt pavement repairs and guardrail installation. By the end of the week, the focus will be on cleaning up the site in preparation for microsurfacing and replacing the lane lines and arrows during the week of September 25. 

As the project nears completion and Ladue Road begins to look more and more normal, please do not use the road until the barricades have been removed. Some of the work must be left to cure, and the city does not want to prolong the closure in order to redo some aspect of this work.

Project Update (September 8, 2017)New drainage by MSD

Laclede Gas finished installing a new gas main well ahead of their September 15 deadline. The city's project to restore Ladue Road to traffic began the week of September 1. Crews will be working to replace the shoulder during the week of September 11. Afterward, repairs including a new guardrail and asphalt pavement will begin.

Crews are working to quickly reopen Ladue Road, and the project remains on schedule to open by October 1. City officials appreciate everyone's patience during this project.

Project Update (September 1, 2017)

The Metropolitan St. Louis Sewer District has completed its repairs to address an erosion issue on the hillside down to the nearby lake. Laclede Gas began their work to install a new gas main immediately following MSD’s completion and is now almost complete with their new main.

The city’s project to restore Ladue Road to traffic will begin with the removal and replacement of the south shoulder of Ladue Road the week of Labor Day. This work is expected to take about a week to complete. Afterward, repairs including a new guardrail and asphalt pavement will begin.

City crews are working to open Ladue Road to traffic as quickly as possible. Staff still anticipates that the road closure will remain in place through the end of September. The city greatly appreciates everyone’s patience during this project.

PROJECT UPDATE (August 23, 2017)Drilling for Piers

Crews completed the primary stabilization repair on August 16, approximately two weeks ahead of schedule. Over 140 concrete piers were built into the hillside to support Ladue Road for years to come.

The Metropolitan Sewer District and Laclede Gas are restoring their facilities in the area. They expect to complete their work by the end of August.

The city has contractors ready to begin the roadway restoration immediately following the utility work. At this point, staff expects the road closure to remain in place through the end of September.
