I-270 & I-70 Project - St. Louis City & County, Missouri

The I-70 / I-270 Project was a traffic safety project to improve pavement surface friction on both urban interstate highways in St. Louis, Missouri.

SCOPE

Microsurfacing Contractors installed nearly 1.5 Million square yards of Micro-Surfacing throughout the I-270 & I-70 corridor. The biggest challenge was coordinating the patching, micro-surfacing, traffic control, and striping work so that each crew could get in a full night�s work and still have the roadway fully opened and re-striped each day by 5AM morning rush hour. On nearly 70 nights, one or more crews worked on this project. There were no accidents or work related injuries. The project was completed on time and under budget.

SPECIFICS

1.5M square yards of Micro-Surfacing 11,000 tons of HMAC overlay 18 miles of traffic control 96 lane miles of pavement markings 8PM-5AM working hours (penalty: $1000/15 minute delay)
