Vanderbilt State Route 27

The route marker sign used for Vanderbilt State Route 27.

Vanderbilt State Route 27 is a highway route currently under construction that begins in Suffolk Village at the northern terminus of Interstate 27 at a concurrency with Colonia Route 31, and currently ends in Cairo with plans to continue northward. The exit numbers of this highway continue where Interstate 27 left off, starting at 37 and continuing upwards; currently the highest exit number is 39. The route starts on Main Street in Suffolk and heads north through the town square, before entering the town of Silvo. As it approaches the town, the route makes a turn westbound onto Dawson Highway and starts traversing into the Sansee Desert, where it soon after intersects with Colonia Route 131 (Levitt Road) at exit 38. At this intersection, State Route 27 turns to the north, where the highway eventually divides into a two-way divided highway. The route currently ends slightly north of Alexandria Street in Cairo, where the concurrency with Route 31 also ends as it turns east onto the local street.
