Geocache Description:

Another Slough cache with some history.

The N Vancouver Avenue: Columbia Slough Bridge is along a corridor formerly travelled by explorers, trappers, and early settlers.

Capt Lewis Love,an early settler, saw opportunity to claim land adjacent to the Columbia Slough southeast of the present N Vancouver Avenue Bridge. The two major roads depicted on an early map, the (“road from Portland to Vancouver”) and a (“county road”) both crossed through Love’s homestead, Love was a farmer, grocery store owner, Justice of the Peace, operated extensive ferry services (hence the title "Captain"), ran grist and saw mills, a steamboat business, and was a hotel owner. His various business aided the growth of Portland, Oregon.


Later a bridge was built across the slough, The date of the first bridge over the Columbia Slough in the current project location is unknown. Although a bridge may have been in place by the 1910s,as it was mentioned in a local newspaper, Crossings at the current project area could have occurred earlier by ferry or raft on the 1850s trail from Portland to Vancouver, which extended to the Columbia River crossing point.

The origonal bridge at this location was completed in 1935, the Vancouver Avenue Access to the Columbia Slough area was important in relation to its connection to the Interstate Bridge and also to the lands reclaimed within the Columbia River floodplain.

The lower Columbia Slough channel was used for floating log rafts to lumber and shingle mills. Other industries along the Columbia Slough’s south bank included meat packing and rendering plants, woodworking, and construction-material manufacturing plants, A rail line constructed circa 1910, which became the Oregon-Washington Railroad & Navigation Company, the Kenton line served the neighboring industries that developed along Columbia Slough and Columbia Boulevard which grew with industrial, residential and recreational uses.

Some businesses, such as the early G.I. Joe’s store that was at the northeast corner of the bridge, benefitted due to their proximity to the Interstate Bridge, which allowed Southwest Washington residents tax-free shopping. Since the construction of the Minnesota Freeway (Interstate 5) in 1966, these feeder roads have lost some of their importance, except to local industry, residents, and businesses.

The bridge was closed to automobile and truck traffic as a result of a fire under the south bridge approach on October 14, 2008 and a new bridge was built.

This project replaced the bridge with a multi-span pre-stressed, precast concrete bridge on the same alignment within the existing right-of-way.

Sidewalks and bicycle lanes were included on both sides of the new bridge. Ramps were needed to accommodate pedestrian and wheelchair traffic transitions between the bridge and the roadway.

Due to the Historical value of the original bridge, guidelines were set for this project and stipulates that the four original concrete end posts of the 1935 bridge be retained and reinstalled at the wing walls of this new bridge.

This new bridge was opened on May 6th 2011 for all to enjoy and thanks for visiting a historical view of the slough…
