On April 29, Chesapeake Bay Bridge and Tunnel District received three design-build Final Technical Proposals and Price Proposals for the Parallel Thimble Shoal Tunnel Project. Each came in at more than $1 billion, with the lowest proposal $292 million higher than the $724.4 million project estimate.
Last August, the CBBT Commission shortlisted the three firms, plus Skanska-Kiewit-Weeks, the JV that is building the Midtown Tunnel. SKW did not submit a formal proposal.
Timelines call for construction to begin in 2017 with completion in 2020 or 2021.

The new tunnel will double capacity at one of two tunnel bottlenecks on the 23-mile-long Chesapeake Bay Bridge Tunnel (CBBT), which provides a fixed link between Virginia’s eastern shore and the Norfolk and South Hampton Roads region on the USA’s East Coast.
The construction of the additional two-lane tunnel will eimprove safety for travelers who utilize the CBBT and protect the economic competitiveness and livability of the region through enhanced resiliency as the CBBT serves as the sole connection between the Delmarva Peninsula and the Hampton Roads area.
