Outside of the Saint Paul city limits, Highway 149 is known as Dodd Road.

The northern terminus of the route is at W. 7th Street / Fort Road near downtown Saint Paul.

By 1981, the route was renumbered 149 when a portion of State Highway 49 through downtown Saint Paul was turned back to local maintenance.

After years of lobbying by Lieutenant (later General) Jesse Reno a remaining portion of the funds allotted to his 1853 survey of the military road from the Missouri River to Mendota which was saved by the work on the Mendota/St.

Peter section by the Dodd crew was awarded by the U.S government to the private builders.
