The green line on the map shows the current undeveloped trail on the Enumclaw side and the paved trail on the Buckley side.  The route of the old highway follows 244th Street E at the center top of the map, goes under the railroad, and crosses the river to align with the beginning of the Buckley trail and River Avenue..  The railroad followed the Enumclaw trail, crosses the river, and aligns with the upper portion of the Buckley trail before it jogs over to the old highway.
The supports for the auto bridge are also still intact on both sides of the river.
There are two auto bridge piers on the Buckley side and one on the Enumclaw side.
Two of the original bridges on the old auto route from Enumclaw to Buckley remain to this day.  This one crosses the flume, which was used to provide water for Puget Power turbines throughout the 1900s.
The existing Foothills Trail follows the old Northern Pacific railbed but before descending to the river makes an S-curve over to the old highway route.  It then crosses this bridge and ends shortly before the old highway bridge abutments and the river.
On the Enumclaw side, the old car bridge over Boise Creek is still in place.

The pipe in the background is a part of a 30-mile  waterline to Tacoma, first built out of wood in 1906.  The old highway passed underneath it.
In the foreground below is the roadbed for the tracks.  The highway passed under the railroad.  You can see the top of a retaining wall for the overpass flush with the ground.  After the highway was abandoned, the gap was filled and the overpass became solid ground.  The railbed is part of the unpaved portion of the current Enumclaw Foothills Trail.
The route of the Foothills Trail connection between Enumclaw and Buckley will follow the old highway route, utilizing both existing bridges and the concrete abutments of the auto bridge across the White River. Green line indicates the existing trail, paved on Buckley side and unpaved on Enumclaw side.  Red shows the proposed route of the link trail between the two.  Blue line is the approximate location of the old rail line and trestle.

This 1939 aerial photo shows the old rail and car routes across the river.  Hopefully, we will be able to cycle from one to the other and back 80 or so years later.
In the 1963 film It Happened at the World's Fair, Elvis rode in the back of a pickup truck on the old highway under the Enumclaw trestle while playing the ukulele.
The above drawing shows the route of the new trail existing south section of the Enumclaw Foothills trail, which will be paved in the coming year.  The drawing below depicts the new bridge that will connect with the Buckley Foothills Trail.
