006-c). These constrained conditions are echoed through the Volume to Capacity (V/C) ratios ranging from 1.501 to 2.5 as identified through the Sarasota/Manatee Metropolitan Planning Organization (MPO) 2050 Long Range Transportation Plan (LRTP) and presented in Table 1-1.
Table 1-1 – 2024 Traffic Volumes and Level of Service Conditions
| 2024 Traffic Volumes and Level of Service Conditions |
| Facility | Limits | Number of Lanes | 2024 AADT(1) | 2024 LOS(2) | 2024 V/C(3) |
|---|
| US 41 Business (SR 45) Green Bridge | Westbound SR 64 to 10th Street | 4 | 41,000 | F | 1.501 - 2.5 |
|---|
| US 41 (SR 55) / US 301 (SR 683) DeSoto Bridge | Westbound SR 64 to 10th Street | 4 | 65,000 | F | 1.501 - 2.5 |

A V/C ratio of greater than 1.0 means that the volume of vehicles on the roadway segment is greater than the volume that the roadway was designed to accommodate when it was constructed. The Sarasota/Manatee MPO 2050 LRTP identified US 41 (SR 55)/US 301 (SR 683)/DeSoto Bridge from 21st Avenue to 10th Street and US 41 Business (SR 45)/Green Bridge from westbound SR 64 to Riverside Drive as two of the top ten most congested corridor segments within the region (ranked #1 and #6, respectively).
Results of the FDOT District One Regional Planning Model (D1RPM) are presented in Table 1-2. Two of the three river crossings will continue to operate at LOS F in 2045 under the No-Build scenario, as conditions will only be exacerbated with the increase in traffic volumes by 2045. Traffic volumes on the Green Bridge and DeSoto Bridge are anticipated to increase by 27.85% and 27.69%, respectively.
