Toothrock Tunnel ("Tooth Rock Tunnel") ...
The Toothrock Tunnel was built in 1936 as part of the Columbia River Highway, today known as the Historic Columbia River Highway (HCRH). The tunnel is 837 feet in length and 28 feet wide, with a vertical clearance of 16 feet. The portals were stone and the lining concrete. The tunnel is located at Columbia River Mile (RM) 146 and is located at milepost 41.16 on Interstate 84 near the Bonneville Dam. Wauna Point, the ridge between Eagle Creek and Tanner Creek, lies upslope. Toothrock Tunnel, along with the Eagle Creek Bridge located just upstream, is one of the few places of HCRH which is used by I-84. Eastbound traffic goes through the tunnel.

"Toothrock" or "Tooth Rock" ??? ...
The State of Oregon Department of Transportation website (2006) and the U.S. National Park Service website (2006) list the tunnel as "Toothrock Tunnel". The U.S. Board of Geographic Names website (2006) lists the tunnel as "Tooth Rock Tunnel".

"The Golden Age of Postcards" ...

The early 1900s was the "Golden Age of Postcards". The "Penny Postcard" became a popular way to send greetings to friends and family. Today the Penny Postcard has become an snapshot of history.
