If you are not running in the marathon, you will want to avoid the area for road closures.
1) Downtown Miami / Bayfront area (Start + Finish)
Expect closures around:
- Biscayne Blvd by the Kaseya Center
- Nearby downtown grid streets around Bayfront Park / the Finish area
- The route also touches the NE 11th St area before heading onto the causeway
If you need to get in/out of downtown: do it early or plan to approach from outside the route boundary.
2) Venetian Islands / Venetian Causeway connection
The course clearly crosses the chain of islands (San Marco / San Marino / Di Lido / Rivo Alto area), which strongly implies closures on the causeway span between Miami and Miami Beach.
Translation: crossing between the mainland and the Beach via that route will be rough-to-impossible during race hours.
3) Miami Beach (big vertical spine closures)
On the Beach, the route runs:
- Up Alton Rd area (mid-Beach spine)
- Over near W 24th St
- Cuts across Dade Blvd
- Then heads down the east side near Collins Ave
- Drops toward South Pointe Dr (and connects via 5th St area)
If you live/work on Miami Beach: expect the Beach to be “segmented” — you may not be able to cross east/west freely in certain sections.
4) MacArthur Causeway + Port of Miami area
The map shows the course on MacArthur Causeway, skirting the Port of Miami.
Translation: getting to/from the Port or using MacArthur as a quick Beach-to-Downtown hop will be heavily impacted.
5) Rickenbacker Causeway (Key Biscayne access)
The marathon route uses Rickenbacker Causeway.
This is the big one: access to Virginia Key / Key Biscayne will be restricted or slowed significantly during the race window.
6) Coconut Grove loop (neighborhood streets will feel it)
The route runs through Coconut Grove using streets that include:
- S Bayshore Dr
- Tigertail Ave
- Grand Ave
- McFarlane Rd area
