Business Loop I-5 - Fife and Midway

When Interstate 5 was opened from near Exit 136 at Fife to Exit 149 at Kent in fall 1962, U.S. 99 was realigned onto the new freeway. Mark Bozanich browsed the March 1967 edition of Washington Highways magazine and noted that a photo on page 10 of what is now the junction of SR 99 (Pacific Highway South) and SR 516 at Midway captured a southbound sign bridge with overheads displaying "I-5 South - Tacoma," "I-5 Business," and "SR 516 - Des Moines."

U.S. 99 was decertified in 1969 and the Tacoma, Seattle and Everett portion of the route became SR 99. SR 99 in turn switched back to the alignment of old U.S. 99 from Fife to Midway.
