Project 4.4.B - S Boeing Access Road from Martin Luther King Junior Way S to E Marginal Way S: Walkway
Improvement
Project Description: Construct sidewalks on the north side of S Boeing Access Road from Martin Luther King Jr Way S
to E Marginal Way S. Re -align the southbound ramps from 1 -5 and Airport Way S that connect with S Boeing Access
Road by creating right -angle intersections. TIP cost estimate to replace all bridges from Airport Way S to 1 -5 is $30.7 M.

Notes:
Contingency raised to 40% because of work on structures. Cost assumes that existing structures can be retained.
Sidewalks built on existing structure for 1 -5 and BNSF bridges, new sidewalks assumed to be constructed on
Airport Way bridge.
