The bridge connects Kentucky Route 313 and Indiana State Road 135, as well as the communities of Brandenburg, Kentucky and Mauckport, Indiana.

It is 3,098 ft (944 m) long and was built at a cost of 5.5 million dollars, financed mainly by the State of Indiana.

The truss portion of the bridge is continuous across two 725 ft (221 m) spans.

The bridge was named after Matthew E. Welsh, the 41st governor of Indiana.

Although 90% of the bridge is within the Commonwealth of Kentucky, it is owned and maintained by the State of Indiana.
