The City of Driggs hired Keller Associates to produce a new multi-modal Transportation Master Plan for the Driggs area (between Stateline Rd, Teton River, 2500N and 2000S). Below you can find information on the project scope as well as project documents. Sign up for alerts or ask a question by emailing Doug Self at dself@driggsidaho.org.
A Final Draft of the Transportation Master Plan was been received from the consultant team and emailed to those who have commented previously and provided email addresses. The plan is available in the files below:
HISTORY: The City of Driggs adopted the previous Transportation Master Plan in 2007, which was last amended by Resolution 258-19 in November of 2019. The newly adopted Transportation Master Plan was adopted by resolution on 11/18/25. The Plan outlines long-term transportation improvements in response to community growth and include a Capital Improvements Plan, roadway capacity analysis, intersection upgrades, bicycle and pedestrian connections, updated roadway cross-sections, and transportation policy updates for the City of Driggs. The purpose of the Plan is to guide the future transportation infrastructure development and ensure it aligns with community growth and priorities. The plan can be reviewed online and at City Hall. The Planning & Zoning Commission considered the proposed resolution during the August 13th meeting and ultimately voted to recommend approval to the City Council. City Council considered the proposed resolution during the September 16th meeting where they ultimately motioned to request revisions to the draft. The City Council again considered the resolution during a public hearing on November 18th, along with the requested revisions, and made a final decision to adopt the "Driggs October 2025 Transportation Master Plan" by Resolution #434-25.

DATA COLLECTION & EVALUATION (Aug. 2024 - Oct. 2024)
Document and evaluate the Transportation System, including road conditions, traffic volumes, bike/pedestrian and transit infrastructure, crash data, demographic and land use data, growth forecasts and existing plans, policies and standards.
Build and utilize a Traffic Demand Model to determine existing and future Level of Service constraints (attach as appendix to the Transportation Needs Assessment)
Meet w/ Project Advisory Team and Interview Project Stakeholders
Growth-driven Improvements. Evaluate forecast volumes to determine the need for additional capacity (e.g., roadway widening, intersection approach widening, or the need for additional links in the roadway network). Review the functional classification of existing streets and make recommendations for changes, as needed. Make recommendations for bicycle and pedestrian network links and extensions.
SH-33 Corridor Study. Coordinate with ITD on projected intersection controls and cross-section improvements. Review City of Driggs Main Street Improvements plan (completed in 2008) and assess the necessity of removal of SH-33 parking to allow for 4-lane expansion. Provide narrative on intersections, alternative route, and corridor improvements that could be future projects with ITD.
Site-specific Improvements. In addition to the above system/capacity related improvements, evaluate existing conditions data for the need of site-specific improvements including: roadway geometry, spot safety improvements, spot pavement improvements, structures, pedestrian facility improvements (e.g. sidewalk, pathways), specific streets identified by the City.
Maintenance Needs. Using the provided pavement condition data, develop roadway maintenance / improvement strategies and associated costs for the existing roadway system. Determine annual roadway maintenance / improvement needs (e.g. chip sealing, overlay, etc.) required to stabilize the condition of the City roadway system. Include discussion of general maintenance strategies and recommendations for streets, pathways, and parking lots, such as repairing and maintaining edges of pavement and seal coating. Provide discussion and recommendations of thresholds to convert existing gravel roads within the City to paved roads. Up to three five-year street pavement maintenance funding scenarios will be analyzed.
Transit System. Review existing facilities and services. Identify opportunities for improvements and how to better integrate with other modes of transportation. Based on feedback from the advisory committee and the public, identify bus stops and on-demand transit system needs. Also identify Park and Ride lot needs. Include strategies and recommendations in a concise narrative.
Roadway Cross-Sections. Provide recommendations for updates to City Standards for roadway cross-sections based on number of lanes, type of street (i.e. land use/zoning location) and functional classification including recommended right-of-way widths, with consideration of complete streets standards and context-sensitive design guidelines. Provide recommendations on how to apply these classifications to new developments.
Policy Updates. Provide recommendations for policy updates on access management, parking, speed limits, street lighting, and truck/freight routes.
Public Engagement. Conduct online survey w/ comment mapping tool, and conduct public open house to collect public input on the above topics.
CAPITAL IMPROVEMENT PLAN (Jan. 2025 - Feb. 2025)
CIP Development. Use the needs identified above, comments received, and engineering judgment to develop a combined Capital Improvement Plan for the City. Specific subtasks to be included in this task are:
a. Develop planning-level estimates of individual project costs
b. Prioritize needs according to safety, mobility, public comment, and funding constraints
c. Organize projects into a short term (3 to 5-year), mid-term (6 to 10-years), and long term (20-year) Capital Improvement Plan and identify annual funding needs
d. Identify potential funding sources
DRAFT & FINAL PLAN (March. 2025 - May. 2025)
Prepare draft transportation plan and submit to City's Project Advisory Team and Local Highways Technical Assistance Council (funding agency) for comments. City will post the draft for public comments (June).
Revise the draft transportation plan based on comments.
Present 2nd draft transportation plan to City Council (City again will post for public comments) - Planning & Zoning Commission Hearing (July), City Council Public Hearing (August)
Revise plan based on comments and submit final plan for City Council adoption (August).
The consultant team interviewed a dozen stakeholder groups representing specific interests (from trucking/delivery to pedestrian safety) or neighborhoods with unique transportation challenges to learn about their particular transportation concerns and needs.
NEXT UP
A 2nd Draft of the Transportation Master Plan has been received from the consultant team and emailed to those who have commented previously and provided email addresses. There are three files below available for review:
Instructions for submitting a public hearing comment are available online at DriggsIdaho.org/public-hearing. Comments received by 5 p.m. Monday, August 4, 2025 will be included in the staff report. Verbal comments can also be presented during the public hearing, by individuals attending in person and via Zoom.
The City has created a Project Advisory Team that meets approximately monthly with the consultant team to help guide their work (see meeting docs here). The members of the Project Advisory Team are: City Planning, Public Works and Community Development Directors, Driggs Mayor, Driggs P&Z Commissioner, Driggs City Council President, Teton County Public Works Director, Idaho Transportation Department District Planner, Teton County Fire Chief, Teton Valley Trails & Pathways Director, Teton Regional Economic Coalition Director, Teton Valley Community Resource Center Director, Teton Adaptive Sports Director.
The new transportation master plan is funded in part by a grant from the Local Highway Technical Assistance Council's Local Rural Highway Improvement Program. Local-option sales tax is funding the remainder of the consultant contract, which has a not-to-exceed amount of $90,000.
