District Chip Seal Operations in Action

ChipSeal CapAnnual Central District chip sealing operations are wrapping up this week and district workers will have logged roughly 100 miles of life-extending treatment on mid-Missouri roadways. Contractors have completed another 200 miles of chip seal, lengthening the life of 300 miles of highway within district borders.


How does chip sealing work?


Chip-seal work includes seal coating the roadway surface to prevent water from entering cracks in the pavement and deteriorating the road. The process consists of placing small aggregate on top of the sealant as it dries. Crews return after the treatment to sweep the remaining loose material from the road surface.


This cost-effective method of roadway maintenance extends the pavement life of the route and makes the road safer by adding texture to improve the skid resistance of the surface.

Holland gets Certificate of Appreciation

Central District Senior Maintenance Worker Curt Holland was recently awarded MoDOT's Certificate of Appreciation for playing a role in saving an individual's life.

On May, 27, 2014, Holland was traveling west in a boom truck on Route 8 near Potosi when he saw a motorcycle and a person lying on the ground. Holland called 911 and during the course of two calls, he directed emergency workers to the accident scene. The victim was airlifted to the hospital. Curt's keen observation and quick actions likely played a role in saving the motorist's life.

We'd like to take the time to recognize Curt and thank him for his continuing service to MoDOT and to the motorists of the state of Missouri.

Time Lapse Video of Bridge Construction

In the last edition of Connections, we published a timelapse video of the demolition of the Route B bridge. This edition we've got a timelapse video of the progress on the bridge to date.

You can find the video to your lower right or at this link:

If you want to track how the replacement of the bridge is progressing daily, you can view a camera that captures bridge images every 10 minutes. It can be found on the project webpage here:

Route B Capture YTConnectBridge pictures, detours and information and videos about the bridge’s innovative construction technique called geosynthetic reinforced soil can also be found on the site. This bridge-building method is faster and less expensive than traditional methods because it eliminates the need for driving costly and time-consuming bridge piles.

The Route B bridge over Business Loop 70 is closed for replacement until Sept. 15. The $881,239 bridge is being built by APAC-Missouri.
