St. Julien Road Reconstruction

Concept Image

St Julien Concept

The Town of Banff is reconstructing and enhancing St. Julien Road between Wolf Street and the Banff Centre in 2022. Construction will continue until October. All underground water and sewer lines are being replaced, private properties will have new utility connections, a sidewalk/trail is being created for the length of the road, new street lighting and storm drainage systems are being added. Renewal will create a safer road for hikers, cyclists and drivers.

Contractor: Bremner Engineering and Construction Ltd (BECL), based in the Bow Valley, was selected as prime construction contractor in a national open tender in early 2022.

Disruption during 2022 construction

During the reconstruction, work will create significant disruptions to the people who live on the street, people who use the street to access Banff Centre, and hikers going to the Tunnel Mountain Trail. Information below is updated weekly with specific disruption impact and detour information.

Tunnel Mountain Lower Trailhead Access Closed

Due to the construction on St. Julien Road, hikers must detour around the construction zone to reach the Tunnel Mountain Trail.  St. Julien Road is a dangerous and often impassable route. The lower trailhead parking lot is closed. Do not rely on Google maps to navigate to the trailhead, use detour signs and the maps below.

Many residents and visitor continue to ignore the signage and have proceeded into the active construction site. This puts them in danger of serious injury or death.

During Sept. 26 - Oct. 2, the total closure for hot mix asphalt work makes it essential that people stay away from the construction site, for their safety and to avoid disrupting the construction schedule. Please help visitors follow the signed detours.

Route options to the upper trailhead:

  • Walk south on Otter Street to Wolverine Street and use the Ken Madsen Path behind the Old Cemetery up to Banff Centre, and then take St. Julien Way to Tunnel Mountain Drive (See map 1 below).
  • Walk on the Buffalo Street trail to Surprise Corner viewpoint, on Tunnel Mountain Drive, and the upper Tunnel Mountain Trailhead (See map 2 below).

The lower trailhead located on St. Julien Road will not be accessible for most of the reconstruction project

Resident-only access details

All properties on St. Julien Road will have full closures of driveway access, all day in the week ahead. No vehicle access will be permitted.

Asphalt paving work is set to start on Sept. 26, starting with a thin oil layer for priming/bonding agent, then paving. This will involve materials that could damage any private vehicles driving on the surface and can be hazardous to people and pets. The work creates dangerous conditions due to the extreme heat of material and the frequent truck movements delivering asphalt, laying the pavement and rollers packing the asphalt. The road closure is necessary for this phase.
The road will be completely closed and no private vehicles will be allowed in the construction zone Sept. 26 – Oct. 2. No one except residents of the street are allowed to walk into the site. 

Bonding Agent: Also known as prime or tack coat, the bonding agent is very hot when wet. It will permanently stick and stain anything including driveways, clothing and vehicles. DO NOT DRIVE OR WALK ON BONDING AGENTS.
Asphalt can be 150 C when it arrives on site to build a road. That is hotter than boiling water! It is very dangerous to pets and people. Do not attempt to drive or walk on freshly placed asphalt or bonding agents (oils), it can damage your vehicle or your shoes, and it can burn you or your dog.
Asphalt remains malleable until it has a chance to cool. Walking on it before it is cool damages the paving, which delays the project schedule and will extend road closures. 

Parking for St. Julien Residents
The temporary locals-only parking areas are specifically for residents of the roadway who cannot access their private driveways to park on their own properties. If you do not live on the street, please respect your fellow Banffites and don’t park there!
The Town’s municipal enforcement team will increase patrols to monitor the four parking zones dedicated to St. Julien Residents. The no parking zones on Wolverine Street will be enforced.
Weekend Construction
The Town has approved extended work hours for the construction crews to complete critical work before snow falls and temperatures drop. Crews will be working this Saturday (Sept. 24) and next Saturday (Oct. 1) starting at 7:30 a.m. and continuing to evening.  If required, the crews will work Sunday, Oct. 2, starting at 9 a.m.

Project Overview

The development will follow the concept design approved by Banff Town Council in 2021 following comprehensive public engagement with local Banff residents. The reconstruction project will:

  • replace and realign the aging water and sanitary sewer pipes under the road
  • replace all utility connections to properties along the road
  • create a separated trail the full length of the road from Wolf St. to the Banff Centre intersection - the trail will be shared by pedestrians, hikers and cyclists heading uphill 
  •  improve the storm drainage for the road
  • resurface the length of the street
  • enhance safety at St. Julien's connections to Wolverine Street and Grizzly Street
  • convert Wolverine Street into a one-way street off St. Julien
  • add stairs and better alignment for a straight pedestrian trail connecting Caribou Street and the St. Julien Trail
  • add more street lighting
  • regrade the access to St. Julien at the bottom of the hill at Wolf Street
  • improve the entrance intersection at Banff Centre

The work will create a safer street for residents and visitors, and a longer lifecycle of the entire infrastructure below and above ground. It will become a more enjoyable route to the Tunnel Mountain trailhead and the street will drain better and snow clearing will be improved.

The reconstruction of the road and sidewalk is based on the Banff Streetscape Design Guidelines for this type of  road, factoring the width constraints and slope challenges of a road on the side of a mountain.

Info Session and Q&A

The Town hosted an online information and Q&A session on April 7, 2022, for residents and interested members of the public. The session provided an overview of the project, what residents who live on the street can expect, the planned schedule, and answers to any questions to the project manager.  The information session was delivered over Zoom using a "webinar" function, allowing the session to be recorded.

More information, such as maps, detour routes, and construction schedules affecting each property will be added to this project page as they are finalized.

Public Input

The Town gathered input on the design options in 2021. (Completed public input: Engagement through walking tours, online forum and surveys and submitted discussion guides provided direction on a number of options for the road design that were presented to Banff Town Council in May 2021. Council approved the final design concept, then set the budget in January 2022.
