By 1930, the entire length of PA 190 was paved along with a section of PA 390 south of Newfoundland. In the 1930s, PA 390 was realigned north of Canadensis and PA 290 was extended north along the former alignment of PA 390 to end at PA 90/PA 507 in Newfoundland.
By this point, by 1930, the entire length of Pennsylvania Route 190 had been paved, as well as a section of Pennsylvania Route 390 south of Newfoundland. In the following years, Pennsylvania Route 390 was reconfigured north of Canadensis and Pennsylvania Route 290 was extended north along the former route of Pennsylvania Route 390 to conclude at an intersection with Pennsylvania Routes 90 and 507 in Newfoundland.
