The Lamoille River Route 15-A Bridge is a modern steel-and-concrete structure, built in 2013 to carry Vermont Route 15A over the Lamoille River east of Morrisville, Vermont, United States.

The old bridge, of Pratt through truss design, was listed on the National Register of Historic Places in 1991,[1] and was dismantled in 2007.

The Route 15-A Bridge is located in a rural area east of the town center of Morrisville.

The bridge alignment is roughly east–west, at a point where the west-flowing river bends temporarily to the north.

It was built using standardized guidelines for bridges of its length (111 feet (34 m)), and used rolled I-beams as a means to speed fabrication.
