Pennsylvania Turnpike Commission in the US has opened new bridges over the Lehigh River & Pohopoco Creek on Northeastern Extension on the Interstate 476 in Carbon County, built at a cost of $101m.

The project to replace two northbound and southbound PA Turnpike/I-476 bridges, which had aged past their service life, began in 2009.

The new twin bridges over the Lehigh River and the Lehigh Canal are 1,530ft long and rise 75ft over the river and canal while the new bridges over the Pohopoco Creek, located north of the Lehigh River span, are 1,020ft long and built 120ft over the creek.

The structures will have four new spans, which will carry northbound and southbound traffic on separate structures, and have a service life of more than 75 years.

The bridges include a 6ft left shoulder and a 12ft right shoulder.
