US 395 Loon Lake Intersection – Safety Improvement Plans – Common questions

What is a roundabout?

modern roundabout is a circular intersection where drivers travel counterclockwise around a center island. There are no traffic signals or stop signs in a modern roundabout. Drivers yield at entry to traffic in the roundabout, then enter the intersection and exit at their desired street. 

Studies by the Federal Highway Administration have found that roundabouts can increase traffic capacity by 30 percent to 50 percent compared to traditional intersections.

They are also proven to be safer than traditional stop sign or signal-controlled intersections.

What is the April 20th meeting about, and what is the timing for this project?
We will discuss the preliminary design for a compact roundabout at the intersection of US 395 and SR 292. Then we’ll hold a meeting in the fall of 2021 to provide an update on the design. The project will go out for bid in the March of 2022 and will be built during the 2022 construction season.

What can we expect during construction?
The compact roundabout is part of a larger project to pave US 395 beginning just south of SR 292, north to Hafer Road. Most likely, compressed work schedules, night-time work and one-lane closures will minimize the impact to the traveling public.

How is this being funded?
The paving project is funded out of the preservation budget designed to preserve our roadways and bridges through regular treatments such as paving and chip seal. The compact roundabout is funded out of the Statewide Systemic Safety program which is optimizing funds to improve safety at intersections suitable for compact roundabouts: smaller size, economical, no need to buy Right of Way.

Will owners of adjacent property be impacted?
No. This compact roundabout will not impact adjacent property or require the purchase of additional land. There will be no sidewalks.

Will pedestrians be able to cross more easily?
Yes, the compact roundabout will have a crosswalk.

Will there be an opportunity to beautify the compact roundabout?
WSDOT is severely resource-constrained so the work must be done quickly, efficiently, and not deviate from the standard plan. There are good looking options within the standard plan for the compact roundabout, such as stamping the concrete. There will not be the opportunity for structures or plantings in the middle of the roundabout because it must be traversable for trucks and other traffic.

Are there examples of similar compact roundabouts?
SR 545 Grandview Road and Kickerville, Ferndale, WA. Similar to US 395/SR 292 size, unmarked outside shoulders, curb cut to prepare for crosswalk in the future. Unlike in that Loon Lake will not have plantings in the middle.
