LINK is made from a “cast-in-place voided concrete deck spanning between transverse reinforced concrete deck crossbeams laid out in a radial pattern” spaced at an average of [1.82m] on center. A pair of upturned cast-in-place, [1.8m x1.8m]-deep, concrete edge girders supports the deck’s crossbeams, creating a U-shaped cross section.

BRIDGE PLAN 1 : 500
STORMWATER: The bridge is designed to capture, clean and convey storm water. The pathway is constructed of permeable pavers that allow water to penetrate through to the subsurface gavel. Water drains horizontally into the rain gardens and also collects in the gutter. As collected rainwater travels along the gutter or filters through the rain garden, it then reaches a downspout which leads into a subterranean 20 000 liter cistern. The filtered rainwater is available for irrigation during dry periods. Located along the edges of the bridge are a series of reinforced circular cast concrete walls that provide structure and support for the bridge’s banks. They also provide space for a series of horizontally aligned cascading rain garden swales. Storm water is directed towards these rain gardens where it filters and slowly infiltrates into the ground. Excess water is redirected through an overflow pipe into the upper north wetland pond of the former Salt Dome Site. 3.15m
The lower substructure of these rain garden embankments is comprised of concrete debris from the decommissioned salt dome site and with excavated soils from the newly dug wetland ponds.

MASTER PLAN 1: 10000
One meter of lightweight engineered landscaping soil supports the native plant species planted along the snaking pathway leading across the bridge. One side of the bridge is planted with hardy drought tolerant native species, while the other side of the bridge is a planted with native wet garden plant species that can tolerate periodic wet spells.

PLANTING AREA
The bridge is 13m wide and provides space for shade producing native trees and shrubs, and a diverse rain garden. It also provides space for rain collecting gutters and for seating. The elevated portion of the bridge creates a 6m high by 38m long passageway for vehicular and rail movement to pass seamlessly underneath.

The LINK Valley Land Bridge spans 468m across Bayview Ave and the CN Rail Corridor. The serpentine path across the bridge touches down on land to meet up with a 173m trail and pedestrian bridge spanning across the Don River and connecting to the Lower Don Trail. The 4m wide pathway across the bridge provides ample space for multidirectional use by cyclists, joggers and amblers alike.

LINK Valley Land Bridge addresses the conflicting circulation interests of pedestrian verses vehicular movement. It bridges the barriers as it gracefully guides the user up and over the dangerous network of road and rail corridors that prevent connection and exploration along the Don River Valley.
