State Road 4 (SR 4) is a two-lane state highway in Escambia, Santa Rosa, and Okaloosa counties in the western corner of the Florida Panhandle. It is signed east–west, but the road is slightly diagonal. The road runs from Century near the Alabama state border at an intersection with U.S. Route 29, to the farming community of Milligan at an intersection with U.S. Route 90. This intersection with U.S. Route 90 is due to be redone in 2015. The road cuts through the Blackwater River State Forest. It crosses the Escambia River, West Fork Big Coldwater Creek, Juniper Creek, Manning Creek, East Fork Big Coldwater Creek, Cedar Creek, Beaver Creek, the Blackwater River, and Penny Creek, all part of the Blackwater River basin (except for the Escambia River). ==Route Description== SR 4 heads slightly southeast from its western terminus at US 29 and SR 95 in Century in Escambia County, just south of the border with Alabama, and crosses the Escambia River into Santa Rosa County after less than 2 miles into its journey. The road then turns and runs east into Jay, where it intersects with SR 89. SR 4 continues east, then gradually turns southeast to its intersection with SR 87, before turning mostly east again and running through Blackwater River State Park.〔(【引用サイトリンク】title=Florida County maps )〕 Shortly before reaching the eastern edge of the state park, formed by the Blackwater River, the road crosses into Okaloosa County and turns southeast again to its intersection with SR 189 in Baker, where it briefly turns sharply south. Curving back to the southeast, the road finds its eastern terminus at US 90/SR 10 in Milligan, just southwest of Crestview.〔 The Florida Department of Transportation annual average daily traffic (AADT) numbers for 2012 show an average of 4,300 vehicles on the Escambia County portion of the road and into Santa Rosa County to Jay, decreasing sharply to 2,600 and then 1,300 vehicles as the road approached its intersection with SR 87. From SR 87 into Okaloosa County the averages increase slightly again to 1,600 per day, and then rise sharply to a high of 7,900 vehicles as SR 4 approaches its eastern terminus from SR 189 to US 90/SR 10.〔(【引用サイトリンク】title=FDOT GIS Geodatabase data )〕〔(【引用サイトリンク】title= FDOT Florida Traffic Online (2012) )〕 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「Florida State Road 4」の詳細全文を読む スポンサード リンク
