Colonia Route 31W

The route marker shield used for Colonia Route 31B.

Colonia Route 31W is an east-west auxiliary route of Colonia Route 31 currently under construction that is to run from the village of Kareen in the west to Suffolk Village in the east. The route is short, only spanning a distance of about 1 kilometer, making it one of the shortest routes on the server.

The route is slated to begin just outside of the walls of Kareen, where it will head west until the route's current western terminus in the center of Vanderbilt City. The route makes a turn to the south for less than half a kilometer on Rockefeller Avenue, past Vanderbilt City Station. This short section of road runs concurrent with Vanderbilt State Route 1, a main street in the city. As the street intersects the southwest corner of the station, it turns eastward again along Chase Boulevard, another main street in Vanderbilt. Once the route crosses the Wyvern River, which makes up the most of the border of Vanderbilt, the road is renamed Islip Avenue as it heads further east towards Suffolk, where the route ends at the junction of 3 other major routes: Colonia Route 31, Interstate 27, and Vanderbilt State Route 27.
