Location

The first bridges were a pair of deck trusses, each carrying two lanes of traffic. The bridges were the site of the groundbreaking of the Turnpike on December 31, 1954.^[1] The bridges, along with the rest of the Turnpike, was opened for a day of free travel on October 20, 1956, between 6 a.m. and 2pm.,^[4] then opened for regular traffic on October 25 at 10 a.m.^[1]

The bridge was widened and rebuilt sometime after 1973.^{[citation needed]}

By 2007, the bridges were considered to be at the end of their design life, and a project to replace the bridges was begun.^[5] The first of the two new bridge was opened to traffic in October 2009, carrying 2 lanes in each direction.,^[2] with the demolition of the old bridge occurring with several blasts, the first of which occurred on November 15, 2009^[6] and the last on January 13, 2010.^[7] The second bridge was completed in late 2010, with traffic moved onto the new bridge on November 29.^[3]
