State Road 426 / County Road 419 Project

State Road 426 Widening Project Outline

About the Project

This is the City's number 1 Transportation Priority. The State Road 426 (SR) / County Road 419 (CR) project is an urban roadway improvement project that will ultimately connect the existing 4-lane roadway at Pine Street (near Oviedo High School) to the 4-lane segment of CR-419 at Lockwood Boulevard, approximately 2.5 miles.

The overall estimated project cost is approximately $83 million and is divided into 3-Phases. Phase 1 addresses downtown (CR-426 / SR-434) intersection improvements. Phases 2 and 3 will make the connection to the west at Pine Street and to the east at Lockwood Boulevard. Federal, State, County and City funds are being combined to accomplish this task. Phase 1 construction plans start this process.


Phase 1 is currently under construction and is anticipated to be complete in the spring of 2018. Phase 2 is currently in design and anticipated for construction in 2021. Phase 2 has not yet begun.  

Project Details

The SR 426 (Broadway Street) / SR 434 (Central Avenue) / CR 419 (Broadway Street) project is primarily the extension of the existing Broadway Street, 4-lane divided / raised median roadway at Pine Street (Oviedo High School), connecting to the existing 4-lane divided / raised median roadway (CR 419) at Lockwood Boulevard, approximately 2.5 miles to the east, through the center of the City's downtown areas. Additionally, the modifications to SR 434 primarily deal with intersection improvements at SR 426, with ancillary modifications at Franklin Street.

SR 426 / CR 419 is an east-west "Principal Urban Arterial" and provides connectivity from SR 417 (Greenway), through Oviedo, to Geneva, Chuluota and east Orange County. It is also the only major east-west roadway segment in Oviedo that is not a 4-lane roadway section.

Phase 1

Phase I planned improvements primarily address the north-south (Central Avenue / SR 434) element of the overall project scope, from Franklin Street on the north to Smith Street on the south.  With planned intersection expansion at SR 426 / CR 419, the two-way traffic movement on SR 434 will be restored through the downtown area.  Improved signalization, additional vehicle stacking / storage capacity and turning movements in both directions will add to the efficiency of traffic operations in this area.
Accommodations for pedestrians will be enhanced as well with sidewalks on both sides of SR 434. This will provide a connection between the Cross Seminole Trail to the south of the SR 426 / SR 434 intersection to the Cross Seminole Trail to the north of this intersection.

Phase 2

Phase 2 will address a major flooding concern at the intersection of South Lake Jessup Avenue and SR 426, as well as addressing other localized drainage issues in the surrounding downtown area. The overall project will also improve environmental water quality with the design and construction of additional stormwater ponds. These ponds will provide regulatory treatment of pollutants within the stormwater, as well as flood control with regulatory peak-flow attenuation of stormwater runoff.

Phase 3

Phase 3 will complete the project with the connection of Phase 2 (4-lane divided / raised median roadway) to the existing 4-lane divided / raised median roadway just west of the intersection of Lockwood Boulevard. This phase is currently unfunded.
