From 1865 to 1870 a wagon road
was built from Vancouver to La Center and on to Olympia. This
road became the main trunk road north out of Vancouver. A
section of this road ran on what is today's NE 10th
Ave. from NE 139th St. northward to Pioneer and then connects to
what is now NE Timmen Rd.
In 1900 this wagon road
became a section of State Highway "1" and at Whipple
Creek the original wagon road was graded and straightened to follow
the section line and a wooden
bridge was built.
In 1915 the state
designated this wagon road as a section of the Pacific
when the state began to pave the highway the old wooden bridge
across Whipple Creek most likely had become unstable and needed to be
replaced. Instead of replacing this bridge, the state just
rerouted the highway down the gully on NE Union Rd. This was
probably done to avoid rebuilding a new bridge and to save the state some
money in the process.
At NE 164th St. The
Pacific Highway was realigned onto what is now NE Union Rd. The
new "State Highway 99" then connected to NE 20th Ave. and then continued
south toward Vancouver. At NE 164th you can still see the
original 1922 pavement on NE Union Rd. before it becomes blocked
by Interstate 5.
So the State Highway
across Whipple Creek lasted for 21 years.
In March of 2018, Clark
County built a new concrete bridge across Whipple Creek where
the old wooden wagon bridge had been. It took almost 100 years
for this section of the old original 1915 Pacific Highway over
Whipple Creek to be reconnected.
I want to thank "Flathead"
Fred for alerting me to this new crossing.
