By 1920, Oregon had of paved roads and of
plank roads for a population of 783,389 and, by 1932, the work that had been started on the
Oregon Coast Highway (also known as
U.S. Route 101) in 1914 was completed, except for five bridges, which meant greater responsibility for the division. This work was complete when the construction of the bridges over the
Yaquina,
Alsea,
Siuslaw, and
Umpqua rivers and
Coos Bay were completed, closing the last gaps in the highway. By 1940, the highway division was managing more than of state, market and country roads in Oregon, with nearly being hard-surfaced. In 2018, the city government of
Portland, Oregon and ODOT entered into an intergovernmental agreement in which the Portland city government takes over the cleanups of transient camps on ODOT right-of-way in select locations in Portland in exchange for payments from ODOT. In 2019, ODOT installed boulders at five locations in Portland to deter transient camps around the freeways. The installations have received support from neighbors while criticized by homeless advocacy groups. ==Exploding whale incident==
