Introduction

In the 1950s, a 4-lane freeway from Frederick to Washington opened as US 240.  It was known as the Washington National Pike.  During the years, the Washington National Pike evolves into I-70S and eventually I-270 in 1974.  Since 1974, I-270 has grown from 4 lanes to 12 as you get closer to Washington.  In the late 1980s, a section of I-270 was known as the "I-270 Technology Corridor", where several Biotech firms call home.
