I-4 and SR 408 Overnight Closures Conclude as SunRail Boosts Spring Break Service

Major Artery Construction and Ramp Closures

Commuters navigating the Interstate 4 (I-4) and State Road 408 (SR 408) interchange should prepare for the final night of significant scheduled work this week. Tonight, Thursday, March 19, 2026, the Florida Department of Transportation (FDOT) will continue overnight closures of the eastbound SR 408 exit ramp to eastbound I-4 (Exit 10B). The closure is scheduled from 8 p.m. to 6 a.m. for widening and concrete operations. Motorists will be detoured via Exit 10A toward westbound I-4, exiting at Michigan Street to turn around and rejoin I-4 eastbound.

In the attractions area, the I-4 eastbound off-ramp to SR 417 northbound and World Drive (Exit 62) remains closed nightly from 11 p.m. to 5 a.m. for ongoing barrier wall installation. Furthermore, the westbound I-4 on-ramp from ChampionsGate Boulevard (CR 532) will be closed tonight starting at 11 p.m. to facilitate lighting upgrades.

Downtown and Local Surface Street Impact

Surface street commuters in the Downtown Orlando area face several ongoing closures due to infrastructure and utility upgrades:

• Summerlin Avenue: Closed between Hillcrest Street and Colonial Drive, as well as segments near South Street, for the Summerlin Improvement Project.
• Magnolia Avenue: Traffic remains blocked between Livingston Street and Jefferson Street through March 24 for the Magnolia Avenue Improvement Project.
• SR 50 (Colonial Drive): Expect intermittent single-lane closures at the Dean Road intersection tonight from 7 p.m. to 7 a.m. for signal maintenance.
• Orange Blossom Trail (OBT): Nighttime single-lane closures continue north of Shader Road and Silver Star Road for widening and drainage work.

Public Transit and Rail Alerts

For those looking to avoid highway congestion, SunRail is currently operating a "Spring Break 2026" promotion. Through March 20, the rail service is providing extended weekday service to accommodate families and spring break travelers. LYNX riders should remain aware of ongoing stop relocations on Links 1, 9, 43, and 102 due to construction work near the Winter Park SunRail station and Maitland Center.

Air Travel and Regional Advisories

Travelers heading to Orlando International Airport (MCO) are advised to allow significant extra time this morning. Reports indicate ongoing TSA staffing challenges have led to increased security wait times; a travel waiver for affected United Airlines passengers is set to expire today. Additionally, motorists heading east toward Daytona Beach should anticipate potential traffic shifts following the implementation of a State of Emergency and curfew today to manage seasonal crowds.
