Work to replace or improve the existing roads began with the construction of a new highway between West Oneonta and modern CR 11A near Laurens that ran along the east side of Otego Creek. The new road was completed by 1932 as a realignment of NY 205, as was an extension of the highway north to Mount Vision. As part of the change, NY 205 was altered between Mount Vision and Hartwick to use a series of highways along the west bank of the creek, specifically Angel Road, current CR 11, and Weeks Road. In late 1932, the section of NY 205 north of Hartwick was closed to traffic as part of a project to completely reconstruct the road. The work was being done by Riteway Construction Company of Saint Johnsville and New York City. The project was completed and reopened . The eastern creekside highway between Mount Vision and Hartwick was upgraded ; as a result, NY 205 was rerouted once again to follow the improved road.
