It also brought unique communication challenges. Residents, commuters and transport companies needed to be kept informed of the blasting schedule as well as the construction timeline.
Adding to the timeline, CDOT recognized a great opportunity for cost savings to expand the westbound tunnel after they completed the eastbound tunnel, given that equipment and teams were already on the ground. But, unlike the eastbound side, there was no third lane on the westbound side. CIG countered the public’s objection to more traffic delays and recreation disruptions for more blasting and construction by emphasizing how the new tunnel would be bigger, wider, safer and more inviting.
The project would be a daily battle of man versus nature, blasting and removing rock, and then fitting a tunnel mold underneath a mountain.
