SR 510/Yelm Loop – New alignment phase 2 online open house – Traffic volumes

Current traffic volumes on SR 510 through Yelm lead to congestion during peak commute hours. Congestion is especially heavy during the summer travel season or when drivers move off of I-5 to avoid incidents. The map below shows 2018 traffic volumes.

This image shows traffic volumes of vehicles per day along the existing SR 510/Yelm Loop roadway.

The SR 510/Yelm Loop improvements will offer drivers a more free-flowing route through the area. The map below shows forecasted traffic volumes in 2022, without Yelm Loop, and how those volumes shift with the addition of the SR 510/Yelm Loop improvements.

This image shows traffic volumes of vehicles/day and travel times in the year 2022. There are two images – the first shows the traffic volumes and travel times without Yelm Loop Phase 2 and the second shows traffic volumes and travel times with Yelm Loop Phase 2. The traffic volumes and travel times are reduced on the main roads with the Yelm Loop.

In 2040, the advantages of the addition of the Yelm Loop will be even more clear, as shown in the maps below.

These images show the travel times in the year 2040 with and without the Yelm Loop. Travel times range between 7 and 17 minutes on the loop as compared to 17 minutes to 29 minutes if the loop was not completed.
