The Aiken Street Bridge was built in 1883 to span the Merrimack River in Lowell. The bridge was renamed the Joseph R. Ouelette Bridge in 1954 in honor of a Ouelette, who was a Lowell soldier killed in the Korean War. The bridge consists of five identical spans, each having a length of 152 ft. It is similar in design to the Washington Street Bridge in Binghamton, N.Y. which consists of three spans crossing the Susquahanna River. Each span of the Aiken Street Bridge consists of eleven panels. The full span length is 675 feet which presents an impressive sight in Lowell. It is the only multispan lenticular bridge in Massachusetts and the only lenticular bridge in Massachusetts that carries a pedestrian walkway on both sides of the bridge. The end posts are constructed as open box sections from four angles and three plates with overall dimensions of 24 in. wide by 16½ in. deep. The top chords consist of an open box section constructed similar to the end posts with 4 angles and tree plates with dimensions of 18 in. by 14 in. Even though the span is shorter than the Bardwells Ferry Bridge, the end posts and top chords are heavier; presumably to accommodate the additional weight of the outer walkways. The bottom chords consist of 1 5/8 in. x 4 ½ in. flat eyebars.
