This street begins at Colorado Avenue S in the west, at an onramp to the northbound lanes of the State Route 99 tunnel, and goes ⅔ of a mile east to Airport Way S. Originally S Connecticut Street, it was renamed in 1979 in honor of sportswriter Royal Brougham (1894–1978), who worked for the Seattle Post-Intelligencer newspaper from 1910 until his death. Such a name change was formally proposed by city councilman George Benson following a suggestion by P-I columnist Emmett Watson. Originally it was to be Occidental Avenue S whose name was to be changed, then the 2nd Avenue S Extension when objections were raised. Finally S Connecticut Street was settled upon; it was thought to be particularly appropriate because he “worked so hard to see the Kingdome built… and eventually spent his last day on earth there.”
Lumen Field, built on the former Kingdome site, is on the north side of Royal Brougham between 1st Avenue S and 4th Avenue S; and T-Mobile Park is on the south side between 1st Avenue S and 3rd Avenue S.
