A two-year reconstruction project of the Lewis & Clark Viaduct began over the weekend, sparking the beginning of traffic challenges for many metro drivers – particularly as they navigate the northwest corner of the Downtown loop.

The Lewis and Clark Viaduct provides a vital link for I-70 across the Kansas River and connects Kansas City, Kansas and Kansas City, Missouri. Following temporary closures – to allow for the installation of traffic control signage for the reconstruction of the I-70 westbound bridge – that began last Thursday, the full closure began on Sunday and will continue to a tentative conclusion of Dec. 31, 2019.

Over the next two years, here is a summary of what motorists can anticipate:

Closures

  • I-70 westbound will be closed past the Broadway interchange (northwest corner of the Downtown loop) to 3rd Street.
  • In KCK, ramps from Broadway Boulevard, Beardsley Road and I-35 northbound to I-70 westbound will be closed.
  • Ramps from I-70 westbound to Minnesota Avenue, Washington Boulevard and the Fairfax Trafficway will be closed.

Detours

  • The main detour route will travel around the Downtown loop or come up I-35 northbound to use I-670 westbound.  The secondary route will use I-35 southbound to the 27th Street exit.
  • To detour to Kansas City, Kansas, use the Central Avenue exit from I-670 westbound.
  • To facilitate traffic operations using the Central Avenue exit, a second lane will be added to the 3rd Street/James Street Exit Ramp from I-70.  Temporary signals will be added to the two intersections.
