to I-IO, Pensacola is better served by highways than any other port city in 

 the region. Descriptions of the highway systems in each county are given in 

 the following subsections. 



Escambia County 



In addition to I-IO, Escambia County is served by east-west highway U.S. 

 90 and U.S. 98. Outside of the Pensacola urban area, these highways have 

 two-lane sections which restrict their capacity at level of service C (Highway 

 Capacity Manual 1965), which is under 10,000 vehicles per day. For compari- 

 son, the capacity of I-IO at level of service C is just under 30,000 vehicles 

 per day. Level of service C is defined as a traffic volume to capacity situa- 

 tion wherein traffic flow is restricted, causing a reduction in travel speed. 

 The major north-south highway serving the county is U.S. 29, which connects 

 Pensacola with Montgomery, AL. 



Santa Rosa County 



Santa Rosa County and Escambia County have the same major east-west 

 arterials. Along the gulf coast, U.S. 98 is heavily used by tourists and 

 generally avoided by through truck traffic. Since the completion of I-IO in 

 the 1970' s, both truck and auto traffic have been diverted from U.S. 90, which 

 used to be the major truck route. The north-south highways in the county are 

 all two lane and lightly traveled. 



Okaloosa County 



This county has essentially the same highway network characteristics as 

 Santa Rosa County. Except for a multilane section of SR-85 linking Crestview, 

 I-IO, and Fort Walton Beach, north-south travel is generally light on circui- 

 tous two-lane roads. 



Walton County 



In addition to I-IO, US-90, and US-98, Walton County is served by SR-20, 

 which links Valparaiso and Niceville with Tallahassee. US-331 is the major 

 north-south route linking DeFuniak Springs with Montgomery, Alabama. 



Bay County 



Major east-west arterials in Bay County are SR-20 to the north and US-98 

 along the gulf coast. The major north-south route is US-231, which links 

 Panama City with I-IO and US-90 near Mariconna, and continues north to Dothan, 

 Alabama. 



Gulf County 



Port St. Joe is linked to I-IO and US-90 at Marianna by SR-71. Along the 

 gulf coast, US-98 is the westbound link to Panama City and the eastbound link 

 to Apalachicola.
