The tunnels were bored in Mount Carmel, essentially under the city of Haifa and have three portals: one from the west, near the MATAM business park (with a connection to the Coastal Highway and the Old Haifa–Tel Aviv Highway), one in the center off Ruppin Road (next to the Grand Canyon Shopping Mall), and from the east connecting to the Krayot (aka the "Checkpost") interchange and Highway 22 at the Yadin/Mevo Carmel interchange.
The project was built by Carmelton, a subsidiary of Ashtrom and Shikun UVinui, two of the largest infrastructure companies in Israel, and the tunnels were bored by China Civil Engineering Construction Corporation (CCECC), a Chinese company specializing in tunnel boring.
In early March 2014 construction was completed on a connector between the tunnels' eastern portal and Highway 22.
A lengthy legal suit followed, which eventually forced the bank to carry out its financial obligations.
The project was first delayed just one week after the cornerstone was laid in April 2007, following concerns over electromagnetic radiation standards.
