What’s Happening in Traffic

UPCOMING: Single lane of alternating traffic on Highway 8

In the coming weeks, overhead sign installations on Highway 8 will require one night with traffic reduced to an alternating single lane. This work is currently scheduled for the night of Tuesday, August 8. Once the date is confirmed it will be shared on electronic message boards at least 48 hours in advance.

Please expect delays during this closure.

An overhead sign is installed over Stoney Trail near 17 Avenue S.W.

All work is weather dependent. Please check 511 Alberta and The City of Calgary’s traffic information map and pathways & bikeways map for information about detours and closures. For all other project information, please visit 

We appreciate your patience during construction.

North Pathway Open and South Pathway Remains Closed

The new permanent pathway connection to the pedestrian bridge on the north side of the river is open and the temporary connection has been removed.

Pathway repairs on the south side of the Bow River to restore sections washed away from heavy rains continue.

Please visit the City of Calgary’s pathways & bikeways map for current information on pathways

Completing the Outlet Control Structures

Outlet control structures regulate the amount of water leaving a storm pond. On the North project, these structures are typically large concrete boxes with an internal weir – also known as a two-cell system – to control the rate of discharge from a storm pond.

As finishing work continues on the stormwater infrastructure, the concrete and maintenance hole covers are being installed on the outlet control structures.

This outlet control structure west of Valley Ridge has been fitted with an emergency remote-controlled gate to manage stormwater during heavy rain or flooding

East of Stoney Trail, the westbound lanes are being paved and a half signal for pedestrians crossing Old Banff Coach Road is being installed. A half-signal is a traffic light that only turns red when pedestrians need to cross.
