Terwillegar Park Footbridge in Edmonton Nearing Completion

The Terwillegar Park Footbridge may be made for an easy walking foot path, but its design is quite intricate.

Just a few days after Edmonton transportation officials displayed the newly completed signature arch of the Walterdale Bridge, the city of Edmonton are celebrating the footbridge as another uniquely designed span crossing over the North Saskatchewan River.

A new milestone was reached on Friday, April 15th, 2016, for the Terwillegar Park Footbridge, as construction crews have completed the installation of 86 precast concrete deck panels which form the pathway surface.

Rob Marchak, the City of Edmonton's director of strategic projects, stated, "It has a very small footprint both for the materials used and a small footprint for building it within this site, But it also has a very slim visual profile, so that's really quite important as well in terms of the impacts in the river valley."

To simulate the span of a rope suspension bridge, the bridge uses stressed-ribbon technology with steel cables embedded within the concrete panels that form a slim profile deck at 46.5 cm thickness.

Supported in the river by 2 piers, these panels are suspended by using 162 individual steel cables anchored to a concrete abutment on the riverbank of each side of the river. The walking deck will gently drape between the piers and abutment.

The construciton of the bridge is on time and on budget. The schedule for its completion is due in the autumn of 2016.

Edmonton will be one of only two Canadian cities that have constructed this type of bridge and the Terwillegar Park Footbridge will be the 2nd longest stressed ribbon footbridge in the world after one in Escondido, California.

The Terwillegar footbridge is 262 metres in length, which is just over the length of 2 professional football fields.

"That's really quite incredible. We've had a lot of visitors both from across Canada and the United States to see how this has gone in," Marchak said.

The cost to build the brdige is $24.5 Million (CAD) and will connect cyclists and pedestrians in Terwillegar Park to River Valley Oleskiw located on the north side of the Saskatchewan river.

"What council was really after when they approved this project was really about improving people's access and connectivity to the river valley. This gives access to more and more people. It opens up the river valley to people who live in the south all the way through to the north."

In 2013, the city received $72.9 million (CAD) in funding from the Alberta provincial government and the Canadian Federal government, via the regional organization the River Valley Alliance, for 5 river valley access projects. The city contributed $1.7 million (CAD). Some of those projects include the Terwillegar Park Footbridge, a funicular, 14 kilometres in the east end, 5 kilometres of new trails in the west end, and 3 new boat launches and seven docks.

The Terwillegar Footbridge is one of the last pieces needed to create a continuous river valley pathway from Devon to Fort Saskatchewan.

"This bridge is a key part of connecting to the south all the way through the Anthony Henday and the existing City of Edmonton trails to the north through Oleskiw Park to the Fort Edmonton Footbridge, which will connect into the balance of the river valley park system," said Larry Wall, executive director of the River Valley Alliance.
