Auxiliary Lanes

Challenge

This diagram shows the entrance ramp at outbound US 290 just past Tidwell. In the current configuration, ramp traffic immediately merges with the right mainlane, forcing highway traffic to slow down, and causing traffic back-ups on the frontage road and intersection.

The proximity of the Fairbanks North Houston exit to the Tidwell Entrance ramp further exacerbates the problem. Drivers entering the highway must immediately decide whether to merge left, travel straight, or exit the highway, all within the same space. This situation can be seen in several areas of US 290.
