Lindbergh Tunnel lane closure due to CO monitor calibration
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
