Lindbergh Tunnel lane closure due to CO monitor calibration

Posted on February 22, 2021 in Media Releases

Project requires lane closure affecting traffic

ST. LOUIS (Feb. 22, 2021): St. Louis Lambert International Airport will calibrate the carbon monoxide (CO) monitors in the Lindbergh Tunnel over a two day period beginning February 23. This project allows the airport and its contractor to calibrate devices that detect dangerous levels of CO gas in the tunnel. These monitors are important for the safe operation of the Lindbergh tunnel. CO gas is colorless, odorless and tasteless and properly working monitors signal when CO levels rise to unsafe levels.

Crews will begin their work, on each of the two days needed for this project, at 9 a.m. They will end their workday in the tunnel at 2:30 p.m. During this time, the tunnel’s digital message boards will relay the current closure to drivers using the Lindbergh Tunnel.

A schedule of the lanes effected by the closure is found below:

Tuesday           Feb. 23                        Northbound Cell                     Right Lane Closed
Wednesday      Feb. 24                        Southbound Cell                     Left Lane Closed
