area, the LOS was calculated only on the two-lane section. The two-lane section between

Surface Transportation Program.
Blair to Omaha
The primary highways in the corridor between Omaha and Blair are US-75 and N-133. US-75

The two-lane section of N-133 between Omaha and Blair and the two-lane section of US-75
between Douglas County and Fort Calhoun are to be upgraded to a four-lane highway in the
