Interstate 205 (I-205) is an Interstate Highway in the Portland metropolitan area of Oregon and Washington, United States. The north–south freeway is 37 miles (60 km) long and serves as a bypass route for I-5 east of Portland. Such a highway was conceived in 1943 plan for the area, and in the 1950s was included in preliminary plans for the Interstate Highway System. Construction began in 1967 with work on the Abernethy Bridge over the Willamette River, which opened in 1970. By 1972, I-205 was extended west to Tualatin and north to Gladstone, but the Portland section was delayed by political opposition until 1977. The Glenn L. Jackson Memorial Bridge (pictured), spanning the Columbia River between Portland and Vancouver, opened on December 15, 1982. The remaining 6.6 miles (10.6 km) in Portland opened on March 8, 1983. From Oregon City to Vancouver, the corridor is paralleled by a multi-use bicycle and pedestrian trail, as well as portions of the MAX Light Rail system. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
