The Holland Tunnel  is a tunnel located underneath the Hudson River. It links up Manhattan, New York and Jersey City, New Jersey.
In search of a Troll, Egon Spengler suggested the Holland Tunnel as a suitable dark and narrow place for a Troll to hide in. He and Peter Venkman drove to the tunnel in Ecto-1 and were stuck in the usual traffic. They spotted the Troll several cars ahead in the back of a truck juggling fruit. Egon and Peter tried to hit it high and low but the Troll jumped onto a passing ice cream truck in the lane heading back to Manhattan.
