3 1. Background Over the last 15 years, the City of Cold Lake has experienced rapid population growth due to the strong economic conditions encountered throughout Alberta. According to the City of Cold Lake Municipal Development Plan (MDP), there will be a significant amount of expansion of commercial, residential, educational, recreational and industrial, especially in the southern region. The City s population is projected to continue to grow at an aggressive pace and could potentially reach a population of 30,000 people by The continuous population and economic growth in the City of Cold Lake will result in increased traffic volumes in the future.

4 Upgrades to Highway 28 will be required to accommodate the future population and traffic. A portion of Highway 28 from 10 Street in Cold lake North to 54 Avenue in Cold Lake South has previously been twinned in Functional study based off of Transportation Study previously completed by the City in 2010.

6 2. Study Area

7 3. Study Objectives Develop a plan that addresses the short and long term roadway issues within the study limits by improving safety, traffic flow and operational efficiency for current and future conditions. Complete geometric assessments and capacity analysis at key intersections utilizing the Transportation Study traffic volumes and provide recommendations for improvements. Develop reasonable access management options balanced with safety and improved traffic flow. Shallow and deep utilities planning. Complete historical and environmental assessment. Identify future right-of-way requirements.

8 4. Study Process Collect background information Develop alternatives Develop intersection improvement alternatives Council Presentation Public Open House #1 Gain feedback from stakeholders and landowners Public Open House #2 Finalize recommended plan and report

9 5. Traffic Volumes and Level of Service Existing Traffic N

10 Future Projected Traffic (20 Year Horizon) According to the Transportation N Master Plan, traffic volumes are projected to more than double in some locations. For example: Existing traffic on west leg of Centre Avenue = 12,800 vehicles per day. Projected traffic on west leg of Centre Avenue = 27,490 vehicles per day.
