 Until 2007 , US @-@ 89 followed State Street to North Temple ( 100 North ) , two blocks from the capitol , but now it turns at 400 South , following the former alignment of SR @-@ 186 and SR @-@ 176 west and north on 300 West , and rejoining its pre @-@ 2007 route at North Temple . In this area , modern US @-@ 89 runs for one block with the UTA TRAX Red Line in its median before crossing the TRAX line in Main Street 's median , then passing the Frank E. Moss United States Courthouse , Pioneer Park , the historic Warehouse District at Pierpont Avenue , Japantown , EnergySolutions Arena , the Arena TRAX station , the Triad Center , and West High School . As it leaves downtown , 300 West curves northwesterly and becomes Beck Street , meeting the modern terminus of SR @-@ 186 at Victory Road at the back side of Capitol Hill .
