Lloyd Concrete pioneers new method for Liberty University Tunnel!

News - April 10, 2014 - 0 Comments - by

Lloyd Concrete has been involved with the new Liberty University Vehicular Tunnel. The four-lane tunnel, scheduled to open by the end of January 2014, is being built under railroad tracks on the west side of campus and will empty out at the Wards Road/Harvard Street intersection. It will have two openings (two lanes entering and two lanes exiting), each with a sidewalk.

The project is an engineering feat! The first time this particular digging method is being used in North America. It involves pulling two jacked concrete boxes (concrete boxes constructed by Lloyd Concrete), each standing 26 feet tall and weighing 4.2 million pounds, through the tunnel from the east side with six motors and more than 160 cables. The tunnel area is more than 100 feet long and crews estimate the pumps will move the boxes about 1 foot an hour. One opening is being dug at a time. The non-stop process is expected to take up to 10 days in all.
