What are the community impacts of tunnel and shaft construction?
Community impacts depend on the shaft locations chosen. Tunnel construction impacts are concentrated at the shafts and can include noise, vibration, dust, truck traffic, and commuter traffic disruptions. These can be minimized with noise barriers, traffic management plans, and other measures. Between shafts, tunnel boring operations have no impact on the surface. Although some people may sense vibration from the boring machine operation, most people never notice the work is going on.
