Oregon

The former route of U.S. Route 99 in Oregon mostly follows routes currently signed as

The first was a general replacement of the original two-lane highway with a four-lane limited-access highway. At that time, the limited-access highway was badged as US 99, and any parallel original route was generally known as "old 99". The second phase was the development of an Interstate Highway, much of which followed the new 99 route and is known as

Decommissioning

By 1968, US 99 was completely decommissioned with the near completion of I-5 in Washington and California, but the highway's phasing out actually began July 1, 1964, when Collier Senate Bill No. 64 passed on September 20, 1963. The bill launched a major program designed to greatly simplify California's increasingly complicated highway numbering system and eliminate concurrent postings. The highways that replaced it are * SR 111 and SR 86 between the Mexico–US border and Indio. *I-10, replacing US 60 and US 70 between Indio and Los Angeles as well. *
