An stretch of the Seward Highway , traveling from Seward to Kenai Lake was completed in 1923 . Another segment of the highway , running between Moose Pass and Hope , was completed in 1928 . The Mile 18 bridge , nicknamed " The Missing Link " , which would connect the Seward and Moose Pass portions , was not completed until 1946 , which was a major cause of the delayed completion of the highway . The roadway was completed on October 19 , 1951 , connecting people Seward to the major city of Anchorage by road for the first time ( the city was previously reached by sea , rail , or air ) . The entire length of the highway was paved in 1952 . During the 1964 Alaska earthquake , about of the Seward Highway sank below the high water mark of Turnagain Arm ; the highway and its bridges were raised and rebuilt in 1964 – 66
