I-90 under construction just east of the East Central area, 1964 (image L87-1.1978-64 courtesy of the Northwest Museum of Arts and Culture)



It is difficult to nail down the completion of I-90 with any precision because crews were building from the west and the east and planning to meet somewhere in the middle. This section, for example, was under construction at the same time as the portion that ran by the South Hill.
