On April 1,
1957, the 47 of the remaining 73 miles of the Pennsylvania Turnpike's Northeast
Extension opened to traffic. Included in the new highway was the
4,461 foot Lehigh Tunnel, a two lane tube through the Blue Mountain.
However by 1970, concerns over the levels of traffic through the 13 year
old tunnel were growing. Throughout the 1960's the Turnpike either
twinned or bypassed the seven tunnels on the mainline system. For
over a decade, various proposals were introduced but tight economic times
did not allow for proactive construction. Finally, in 1985, Act 61
authorized new funding for the Pennsylvania Turnpike System. The
legislation approved funding for the twinning of the Lehigh Tunnels. Studies
began almost immediately and construction began early in 1989. Construction
would last for nearly two and a half years, ending with the opening of
the new facility on November 22, 1991.
Throughout the 32 months of construction, Bill Symons took photographs of the progress made. He begins with an untouched south portal in 1989 to the tunnels a few weeks before opening in the fall of 1991.

Be sure to notice the change in the hillside from this photo in 1989 and the following two. Excavation work has begun and the concrete superstructure is beginning to take form. (Bill Symons) |
Substantial progress can be seen by the Autumn of 1990. A wide double yellow line and guard rail is all that separates the opposite direction of traffic entering and exiting the tunnel. (Bill Symons) |
