The road is mainly a good quality two-lane highway.

Highway 19 passes through the following municipalities: Kurikka–Ilmajoki–Seinäjoki–Lapua–Kauhava–Nykarleby. It starts at Kurikka's Jalasjärvi, where it diverges from Highway 3 (E12).

From Seinäjoki, the road continues through the municipalities of Lapua and Kauhava to Ytterjeppo, Nykarleby, where it joins Highway 8 (E8). An eastern bypass was built from the road, which opened to traffic in November 2015 and facilitated better access from Seinäjoki to the south.
