However, in 1955, the state doubled tolls to $1.80 round trip for cars (equivalent to $ in dollars) and $4.00 or more for trucks (equivalent to $ in dollars) in order to pay for repairs, new toll booths, and a new punched card system compatible with the Hampton Roads Bridge-Tunnel. The toll plazas, which had numbered three - one for each bridge - were consolidated to two, one at the south end of the main bridge and one at the north end of the Nansemond River Bridge. Thus the Crittenden Bridge became free for local traffic. In addition, passenger vehicles and light trucks only had to pay at the first booth they reached; large trucks and buses had to pay twice. This meant that light vehicles crossing only the main bridge (for instance between Smithfield and Newport News) only had to pay southbound.
