|Route outline (key)|
The road started on the L24 (now N3) on the border at Belleek and headed eastwards and ran along the southern shore of Lower Lough Erne to reach Enniskillen and the A4. There was a short multiplex southwest out of town before the B37 continued southwards along Upper Lough Erne (albeit never properly coming within sight of the water). It ended on the border at Aghalane Bridge a short distance on the north side of Belturbet, once again becoming the L24 (now N3).
The section north of Enniskillen was quickly upgraded to Class I status, becoming the A46 in the mid-1920s. As the southern section did not lead to an approved border crossing, with less traffic as a consequence, the B classification lasted longer before the road became the A509 in the 1960s. The B37 number is, therefore, no more.
