Bravo Environmental purchased a tunnel tour for 10 people at the annual NUCA of WA auction. The tour package, including lunch, was kindly donated to the auction by the Seattle Tunnel Partners in support of NUCA of WA.
We invited engineering and construction professionals on the 4 hour tour. Everyone was very impressed with the scale of the project and the STP team. Bertha is the worlds largest tunnel boring machine- She’s a big girl!
