The entire road forms part of National Route 231 (N231) of the Philippine highway network.

The Lower Session Road extends eastward from Magsaysay Avenue (opposite the Plaza or kilometer zero and Malcolm Square) running through the BCBD until the intersections of Father Carlu Street (towards the Baguio Cathedral and Upper Bonifacio Street) and Governor Pack Road.

This is the area where businesses are located, among others banks, shops, restaurants, bakeries, hotels, newsstands, boutiques, and studios.

The Commission was composed of Governor General Luke E. Wright, president, and Commissioners Henry Ide, Dean Conant Worcester, Trinidad Pardo de Tavera, Benito Legarda, Jose de Luzuriaga, James Francis Smith and William Cameron Forbes.

During World War II, the road was almost obliterated when the Americans bombed Baguio to liberate it from the Japanese.
