U.S. 101 north
U.S. 101 begins at Tumwater and follows a freeway west six miles to the historical split with U.S. 410 (Washington 8). The US route straddles the Olympia city line west to a diamond interchange with Cooper Point Road / Capitol Auto Mall Drive west and Crosby Boulevard south. Photo taken 09/02/06.
The first reassurance marker posted for U.S. 101. Technically the end at Tumwater is the northern terminus, but U.S. 101's alignment encircles the Olympic Peninsula, resulting in southbound heading northbound to Discovery Bay. Photo taken 09/02/06.
U.S. 101 shifted from an alignment using Mud Bay Road, Harrison Avenue and 4th Avenue to the freeway south of Olympia in 1958. Cooper Point Road leads north from Capitol Auto Mall Drive to Capital Mall and Cooper Point on Puget Sound. Crosby Boulevard winds southward from U.S. 101 around Tumwater Hill to Sapp Road.

U.S. 101 south
Approaching the Tumwater city line, U.S. 101 takes its final approach to Interstate 5. The southbound ramp to Interstate 5 includes a connection with 2nd Avenue SW ahead of Custer Way. Photo taken 09/02/06.
U.S. 101 south defaults onto Interstate 5 north at a tri-level stack interchange opposite Capitol Lake. Photo taken 09/02/06.
Interstate 5 replaced U.S. 99 as the main route between Portland, Oregon, Olympia and Seattle, Washington. Interstate 5 and the U.S. 101 freeway at Olympia/Tumwater opened in 1958. U.S. 101 doubled as U.S. 410 east from Mud Bay to Interstate 5 until its decommissioning in 1967. U.S. 99 was decommissioned in 1969, two years after Interstate 5 was extended east into Pierce County. Photo taken 09/02/06.
