The City of Edmonton is conducting a planning study to update the 2001 Terwillegar Drive freeway concept plan to meet consider the City’s growth, as well as changes in the overall transportation network and roadway design standards.

The outcome will be a free-flow freeway (no traffic signals) between and including Whitemud Drive and Anthony Henday Drive.

The The City is also conducting a survey to help develop the Terwillegar Drive Concept Plan Update. Please remember to take the Survey, if you haven't taken it yet.

    Could the City provide online traffic flow maps for each Option presented? There is considerable confusion as to the traffic flow options available in each scenario. For example, for North Section Option B: if someone would like to travel from Bulyea Heights or Rhatigan Ridge heading northbound onto the Whitemud freeway- what exact path(s) could they take (please be specific)?

    An analysis of the impacts to traffic redistribution is a consideration in this study and is currently underway. The study team is also meeting with the adjacent communities for input on priorities and impacts. It is anticipated the results of the traffic redistribution on other routes, such as 40 Avenue and Riverbend Road, will be shared by the next public meeting. No final recommendation has been made.

    Where are the Engineering studies for the redesign of Terwillegar Drive? Can you send them to me or provide a link?

    Craig Eastman Asked over 2 years ago

    Each of design options is currently being fully evaluated to understand how the freeway and neighbourhood roadways would function, as well as the resulting impacts. 

    No decisions have been made on the freeway or interchange design options.

    When will the city finish the doubling of Rabbit Hill Rd along the east side of Terwillegar Towne (S. Terwillegar Dr. to Terwillegar Blvd.) to handle the traffic increase there because the Haddow access is apparently going to be removed? Rabbit Hill Rd has to be finished first or at least be part of this plan!!!

    Andrew Asked over 2 years ago

    Funding has been approved and the Rabbit Hill Road widening is planned for 2019 construction.

    What does the City’s existing traffic model say about the traffic impacts on Riverbend Road with the two options for 40 Avenue?

    Larry Bodnaruk Asked over 2 years ago

    Each of design options is currently being fully evaluated to understand how the freeway and neighbourhood roadways would function, as well as the resulting impacts.

    Is it possible to redesign the Whitemud & Terwillegar Drive interchange so that one can drive straight down Terwillegar drive north to the 53 ave overpass? Right now drivers are required to drive along Riverbend road and by various playground and school zones.

    DJD Asked over 2 years ago

    It is anticipated the access to/from 53 Avenue and Whitemud Drive/Terwillegar Drive will remain unchanged. This is due to the short spacing between Terwillegar Drive and 53 Avenue (approximately 850 m) and the associated complexities adding access to/from 53 Avenue and Terwillegar Drive. This is unchanged from the previous planning studies.

    I saw Shared-Use Paths and BRT would "possibility" to be included, but don't see any rendering on the plans except for SUP bridges. Will they be provided in all options or some?

    SUP Asked over 2 years ago

    All modes of travel are being considered, including pedestrians, cyclists and transit.  Cyclists and pedestrians will be accommodated on the roads crossing Terwillegar Drive, including a future shared-use path across Whitemud Drive between the communities of Bulyea Heights and Brookside.  The location of bicycle accommodation is being guided by the City's Bicycle Transportation Plan (https://www.edmonton.ca/transportation/cycling_walking/bicycle-transportation-plan.aspx).  This study will also consider future transit needs identified in the Transit Strategy, the City's long-term vision for transit. The future transit needs on the corridor, including precursor BRT, will be fully examined in the Bus Network Redesign project, which is anticipated to be completed in 2018. 

    The detailed shared-use path and transit plans will be developed as the study progresses.

    Can the City of Edmonton confirm whether a study or studies were done on the improved Whitemud traffic to and from Anthony Henday Drive with an improved south bound interchange at the west end to Anthony Henday Drive to replace the lights, and the upgrade to the interchange at Terwillegar Drive and Anthony Henday Drive.

    Myron Asked over 2 years ago

    As part of this study, a detailed analysis of future traffic volumes is being conducted. This analysis includes includes an approved plan to update the Anthony Henday Drive and Terwillegar Drive interchange.  The approved interchange plan can be found on the study's website at edmonton.ca/terwillegardrivestudy

    Why not do a 3-day to 1 week traffic impact study NOW, by blocking off 40 Ave-Bulyea? I have suggested that option B would cause immense backups both in the communities and out on to Terwillegar and Whitemud. You have the opportunity to try it right away before you commit! Sure, there is no flow through at Rabbit Hill Road, but that is a small percentage compared to people exiting at 40/Bulyea and R.H.Rd. And a side question: What is wrong with keeping it like it is? It's not really broke apart from improving the light timing a bit.

    Alister Asked over 2 years ago

    The City has previously conducted trials to analysis the impacts of roadway changes in advance of full implementation.  As this is early in the study and no decisions have been made on an option, traffic trials are not planned. 

    Traffic analysis considering future traffic projections is currently being conducted to assist with decision-making.

    In the planning materials, it is indicated that there is a desired weaving distance of 2 km. Can you please indicate what is typical in the city as well as minimums, maximums and the average?

    CKS Asked over 2 years ago

    Approximately 2000 m of spacing is desirable, but may be more or less depending on speed, traffic volumes, and the use and placement of on/off ramps. On Whitemud Drive, the typical spacing between interchanges is about 1600 metres, but less in some locations. For example, the spacing between 111 Street and 119 Street is 1300 m and experiences some operational issues. When the spacing is less than 1600 m, then consideration is given to consolidating access to/from a freeway using collector/distributor roads (service roads) such as along Whitemud Drive between 159 Street and 178 Street.

    I have finished the survey. How do I know it has been sent to the City?

    George Inch Asked over 2 years ago

    The survey is set up to automatically redirect respondents to the Terwillegar Drive Study main webpage. Unfortunately, there is no confirmation email. We appreciate hearing from you and will consider improvements for future surveys.
