State Route 133 or SR-133 is a mostly multi-lane highway and is a primary artery through Muscle Shoals and Florence in northwest Alabama. The route begins at SR-20 (Alternate US-72) just south of Muscle Shoals. It runs north along Wilson Dam Road, becoming a six-lane highway at Avalon Avenue. It crosses the Tennessee River and enters Florence on the new Patton Island Bridge. From there, it narrows to four lanes and runs east along Veterans Drive to Cox Creek Parkway. It follows Cox Creek Parkway as it forms a northern loop around the city of Florence, though there is extensive retail development along most of the route. SR-133 and Cox Creek Parkway end northwest of Florence, again at the intersection of SR-20 (known locally as Savannah Highway). ==History== SR-133 was likely formed around 1927 with the completion of Wilson Dam on the Tennessee River and the opening of it to automobile traffic. At this time, the route would have started at an old alignment of SR-20 just a few hundred yards north of its current alignment. It followed Wilson Dam Road north through Muscle Shoals to the TVA Reservation. Here it intersected Reservation Road, running east to the Dam. Crossing the Dam it would have entered Florence and followed Wilson Dam Road, just east of the current Cox Creek Parkway alignment. It ended at Huntsville Road, which at the time carried U.S. Highway 72. In the mid-1950s, U.S. 72 in Florence shifted to a new alignment on Florence Boulevard, about one-half of a mile north of Huntsville Road. It is unclear, but SR-133 may have taken Middle Road to between Huntsville Road and Florence Blvd. to reach U.S. 72. Also around this time, SR-20 south of Muscle Shoals shifted southward to a new routing, extending the route south about 300 yards. Big changes occurred in the early 1970s with the construction of Cox Creek Parkway, a northern loop for the city of Florence. The new road placed SR-133 on a four-lane highway for the first time. From Wilson Dam, Cox Creek Parkway replaced Wilson Dam Road to carry SR-133 to Florence Blvd. From there, the route was extended some seven miles along the entirety of Cox Creek Parkway. In 2002 the Singing River Bridge (Patton Island Bridge) opened, forming a new Tennessee River crossing one mile west of Wilson Dam. As part of a long-term "Patton Island Corridor", SR-133 was shifted to this new six-lane bridge. The move necessitated construction of an overpass on Wilson Dam Road on the TVA Reservation. SR-133's routing on Reservation Road and Wilson Dam itself was removed. After crossing the new bridge into Florence, the route turned east on Veterans Drive to rejoin Cox Creek Parkway just north of Wilson Dam. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alabama State Route 133」の詳細全文を読む スポンサード リンク
