Inglewood Bridge

The 9th Avenue SE Inglewood Bridge built in 1908-1909 served the City of Calgary for 110 years. The heritage value of this structure comes from its Parker Camelback design that was a popular style used throughout North America of which this bridge was representative of [1]. This design was also the most frequent used in Calgary from 1887 to 1912 with the MacDonald bridge (1911) crossing the Elbow, the Reconciliation (1910) crossing the Bow, the Hextall (1910) crossing the Bow, and the St. George’s Island (1908) bridges still serving as surviving representations of this era and design [1]. Due to reduced carrying capacity, a failure to meet modern design and engineering standards, and insufficient flood resiliency the Inglewood Bridge was scheduled to be removed in July 2019 and replaced with a more modern structure that could better serve the needs of the city [2]. As part of Calgary’s heritage in the city’s oldest neighborhood, this bridge was documented with terrestrial laser scanning before its removal.

Digitally Capturing the Inglewood Bridge

The Digitally Preserving Alberta’s Diverse Cultural Heritage project approached the City of Calgary to document the 9th Avenue SE Inglewood Bridge before its removal and subsequent replacement. The bridge was first documented on June 22, 2019 with a Z+F 5010X scanner and approximately 20 mounted paper targets. However, on this date the bridge was still in operation and due to the vibrations of the bridge deck as traffic drove by the scanner was unable to complete scans on the bridge itself. On this day only the east and west end portions of the bridge could be captured.

The project returned on July 18, 2019 when the bridge had been closed to the public to complete the documentation process using the Z+F 5010X scanner. On this day two scanning projects were completed. The first to capture the top of the bridge and the bridge deck, using a combination of six paddle targets and approximately 12 mounted paper targets with a total of 14 scanning locations that zig-zagged across the bridge. The second smaller project to capture below the bridge along a closed bike path below the west side, using six paddle targets with a total of five scanning locations that followed along the available pathway. The scanning projects were individually registered using Z+F Laser Control software and then exported into AutoDesk ReCap to be combined. The resulting point cloud is a combination of the two scanning projects from this later date.
