On-Alignment Rural Concepts
Concept: Rural Widening
On-Alignment | Widening US-95 outside Moscow on the current highway alignment
Level One Screening Result: Carried Forward
Key Components
Consistent four-lane cross section would be considered on the existing highway system where possible. This would be considered north of Moscow (starting at milepost 347) to the Latah/Benewah county line.
Four lanes may be divided (top image) or undivided (bottom image).
Map graphic indicates generalized areas for potential improvements. Exact locations would be refined throughout the study.

Concept & Options: Rural Improvements
On-Alignment | Targeted roadway improvements outside Moscow city limits
Level One Screening Result for Each Option: Carried Forward as Elements
We considered stand-alone improvements to the existing roadway.
Each of the following options were carried forward as elements:
-
Shoulder Widening
-
Passing Lanes
-
Turn Lanes
-
Roadway Signage
-
Wildlife Movement
-
Geometric Improvements
Map graphic indicates generalized areas for potential improvements. Exact locations would be refined throughout the study.
Details for Concept Options: Rural Improvements
Passing Lanes
Passing lanes may be considered in rural areas in a variety of configurations as dictated by geography and roadway engineering best practices.
Graphics are for example purposes only; ITD requires 1.5-2 miles for many passing lanes, and much longer lengths will be considered, dependent on terrain.
Turn Lanes
Turn lanes may be added to facilitate heavy traffic movements and improve intersection operations.
Graphic is for example purposes only; a combination of through lanes and left- and right-turn lanes would be considered.
Geometric Improvements
A geometric deficiency is a roadway element that doesn’t meet current design standards. These deficiencies may not necessarily indicate higher levels of risk but are rather a way to note the difference in how the road
was built in the past and how we would design it today. When we look at upgrading a roadway, we want to consider improving the road to current design standards where it makes sense.
These improvements may address:
-
Curves in the road, both vertical and horizontal
-
Sight distance
On-Alignment Urban Concepts
Concept & Options: Urban Improvements
On-Alignment | Targeted roadway improvements in Moscow
Option: Lane Reallocations
Level One Screening Result: Carried Forward
Graphic for example purposes only to depict possible lane usage for parking adjustments
Some considerations we may look at for lane reallocations include:
Parking adjustments
-
Third Street between Washington Street and Jackson Street could add an additional westbound lane
Turn lanes or minor widening
-
Washington state line to Line Street
-
Jackson Street from Gritman Medical Center through the Washington Street intersection to maximize capacity within the existing roadway

On-Alignment | Targeted roadway improvements in Moscow
Option: Access Management
Level One Screening Result: Carried Forward as an Element

Concentrating left turn movements to specific streets can increase safety and capacity on narrow, busy roadways.
Left turn access management (potential removal of left turn movements) would be considered at the following streets:
-
Spotswood Street
-
Jefferson Street
-
Veatch Street
-
Lilly Street
-
Almon Street
-
Alsbury Street
Graphic indicates generalized areas for potential improvements. Exact locations would be refined throughout the study.
On-Alignment | Targeted roadway improvements in Moscow
Option: Signal Operation Improvements
Level One Screening Result: Carried Forward as an Element
Optimization of signal timing, including queue management and a review of flashing operation, will be analyzed.
Potential new traffic signal locations will be analyzed throughout the process. New traffic signals may be warranted dependent on future traffic growth and other planning efforts.
Graphic indicates generalized areas for potential improvements. Exact locations would be refined throughout the study.

Concept & Options: Urban Walking & Bike Improvements
On-Alignment | Standalone improvements for walking and biking in Moscow
Options may include: Improved Connection to Latah Trail, Bike Lanes on Roadway, Enhanced Pedestrian Crossing, Mid-Block Crossing
Level One Screening Result: Carried Forward as an Element
Targeted improvements for walking and biking facilities would be considered for the current highway system. While the details of specific improvement elements would be identified and refined in Level Two, we anticipate considering options such as:
-
Improved Connection to Latah Trail
-
Bike Lanes on Roadway
-
Enhanced Pedestrian Crossing
-
Mid-Block Crossing
Option: Marked Crosswalk
Level One Screening Result: Eliminated
-
Marked Crosswalks were considered but Eliminated. At the current highway speeds and volumes, marked crosswalks without supporting infrastructure are less safe for pedestrians.
-
As shown above, other walking and biking improvement options will be carried forward as elements.
