Road block

Look closely at I-70 for  the black dot...a car about to pass through

RICHFIELD, UT - - The San Rafael Reef is an imposing 75 mile long geological feature of the Colorado Plateau in central Utah.  In the early days of the territory a long detour was the norm.  So daunting is this 'uplift' that it wasn't until 1970 that a two lane road could be constructed through.  Not until 1985 did I-70 make the connection between east and west UT a two lane (each way) high speed reality.
