Last spring, The City of Calgary, Rocky View County and Alberta Transportation initiated a study for a half interchange at Glenmore Trail / Highway 560 and 100 Street S.E. The study focused on providing access to and from the west to accommodate the highest demand movements.
The current plan for the future interchange at 116 Street S.E. will shift the existing road west to avoid a large wetland in the northeast corner of the intersection. This means the planned interchange at Glenmore Trail and 116 Street S.E. would be too close to 100 Street S.E. for ramps to and from the east at 100 Street S.E. to operate effectively and safely.
During Phase 1 of the Glenmore Trail / 100 Street S.E. interchange study, stakeholders asked us to investigate the possibility of a full interchange. They also asked us to identify possible short-term improvements to reduce congestion at the intersection of Glenmore Trail and 100 Street S.E.
Based on several factors, including public input, planned development in the area and the shifting role and function of 116 Street S.E. in the transportation network, Alberta Transportation has agreed to expand the study area to include 116 Street S.E. The two interchanges will now be reviewed together to identify the best access for both. We will also identify possible short-term improvements to reduce congestion at the intersection of Glenmore Trail and 100 Street S.E. The study name has been revised to reflect the new study area.
The City of Calgary, Alberta Transportation and Rocky View County are working together to make joint recommendations for future interchange plans on Glenmore Trail at 100 Street S.E. and at 116 Street S.E. This study will identify the interchange layouts, the land required to build the interchanges and how access will be provided to the bordering lands. The future interchanges are not anticipated to be constructed for 20 – 30 years.
Study background and purpose
The study area involves three governing bodies:
- Glenmore Trail (called Highway 560 east of Stoney Trail) is a Provincial road managed by Alberta Transportation
- Lands south of Glenmore Trail and west of 116 Street S.E. are within City of Calgary
- Lands north of Glenmore Trail and east of 84 Street S.E. are within Rocky View County
100 Street S.E. is also known as Garden Road or Range Road 285. 116 Street S.E. is also known as Conrich Road or Range Road 284. Glenmore Trail/Highway 560 is a designated high load corridor for trucks, so any future interchange must provide a bypass for trucks with high loads to get around the bridge.
The intersection of Glenmore Trail and 100 Street S.E. was identified for closure in a February 2007 Functional Planning Study. The currently approved plan shows 116 Street S.E. shifted west of the existing intersection. In the years since this plan was approved, the East Regional Context Study, Shepard Industrial Area Structure Plan (ASP) and Janet ASP have been approved and increased development in the area is expected. As a result, The City of Calgary and Rocky View County need to provide access to the lands around these intersections.
Alberta Transportation has agreed to explore interchange layouts that provide the best access while meeting the highway requirements.
The Glenmore Trail East Study will include the following outcomes:
- Determine long-term needs for capacity, lane configurations and land (right-of-way) requirements
- Identify the impacts to properties in the study area, if any, and prepare an access management plan to establish access to bordering properties when the interchanges are constructed
- Identify the interchange plans and profiles that accommodate and consider:
- High load trucks on Glenmore Trail, 100 Street S.E. and 116 Street S.E.
- Tie-ins to other interchanges and the surrounding road network
- Transit priority
- Pedestrian and cyclist mobility
The City of Calgary, Alberta Transportation and Rocky View County recognize that decisions are improved when stakeholders and citizen input is included throughout the study process.
The project team has developed a three-phased engagement program for the project, with opportunities for stakeholders and citizens to provide feedback during each phase of the study.
Information session - June 15, 2015
An information session was held on June 15, 2015 to introduce the project team, provide information about the study and discuss any issues or concerns about the proposed interchange. More than 60 people attended and 18 comment forms were submitted. The feedback form was available on this web page from June 16 - 22, and an additional 46 comment forms were submitted online.
Respondents were most concerned about maintaining access from the east and existing traffic congestion. Several respondents indicated that constructing the interchange in 20 – 30 years is too long and short-term improvements are needed. For detailed information about the information session, please view the display boards, comment summary and the verbatim comments from the feedback forms.
Issues Scoping Workshop – June 25, 2015
Representatives from The City of Calgary, Rocky View County, Alberta Transportation and power transmission utilities (AltaLink, Alberta Electric System Operator and ENMAX) were invited to attend an Issues Scoping Workshop June 25, 2015. The purpose of the workshop was for technical experts to identify issues, concerns and constraints prior to developing concepts for the future half interchange.
Some of the topics discussed included high loads ramps and high load traffic requirements, preserving or managing the surrounding wetlands, accommodating wildlife movement, the existing power lines, residential access and the local road network. The input received will be used to facilitate developing and reviewing options for the future interchange.
Stakeholder and adjacent landowner meetings – August/September 2016
The project team met with key stakeholders and all adjacent landowners – seven groups in total – to review preliminary interchange options. Landowners were most interested in minimizing right-of-way requirements, providing a full interchange at 100 Street S.E., and keeping 116 Street S.E. on the current alignment.
Options Evaluation Information Session – November 16, 2016
There were 52 people that attended the open house and five of them submitted their feedback forms at the event. There were 58 feedback forms completed online.
- The majority of the respondents (48 respondents, 83%) felt the proposed short-term improvements at 100 Street S.E. would improve traffic flow.
- Responses varied for which interchange configuration (diamond interchange or diverging diamond interchange) was best suited for 100 Street S.E. or 116 Street S.E.
- Wetlands and environmentally sensitive areas were the environmental factors that received the most responses as an important environmental consideration.
- The social factor that received the most responses for being an important consideration was local connectivity.
- The two economic factors that received the most responses for being an important consideration were road safety and travel time / operations. For detailed information about the information session, please view the display boards and What We Heard Report.
The project team will evaluate the interchange options using public input and triple bottom line analysis and select and refine recommended plans for 100 Street S.E. and 116 Street S.E. In spring 2017 the project team will meet with adjacent landowners to share the evaluation results and present the final plan, including access locations and right-of-way requirements. The public will also be invited to a final information session in spring 2017 to view the final plans.
