SCOPE OF WORK
SUPPLEMENT 4
January 28, 2025
A.PROJECT BACKGROUND / DESCRIPTION
will resurface approximately 6,000 LF of SW 43 rd Street from
approximately 200 feet east of the Renton/Tukwila City boundary vicinity of the
Interurban Trail and BNSF crossing eastward across SR 167 to the Northbound SR 167
ramps intersection (including the intersection). This project will also upgrade all curb
ramps along the corridor's intersections.
For the purposes of this scope, the following improvements were assumed:
Grind and overlay SW 43rd St from the western City limits eastward to the NB SR
167 ramps, except where there are existing concrete panels
Full depth pavement repair where alligator cracking is present (along SW 43 rd St
from Renton/Tukwila City boundary eastward to the NB SR 167 ramps
intersection).
Replacement of existing curb and gutter segments where severe deterioration
is observed (along SW 43rd St from Renton/Tukwila City boundary eastward to
the NB SR 167 ramps intersection).
New curb ramps at the intersections of SW 43rd St/Oakesdale Ave SW, SW 43 rd
St/Lind Ave SW, SW 43rd St/East Valley Hwy (all four corners, including the right
turn slip lane to island crossings on the NE and SW corners of the intersection),
and new curb ramps for SW 43rd St/NB SR 167 ramps intersection (all four
corners, including the right turn slip lane to island crossing on the SE corner of
the intersection).
New channelization on SW 43rd St from the western City limits to the east of the
NB SR 167 ramps intersection.
Upgrade traffic loops with new video detection where disturbed by asphalt
grinding operations at the intersections of SW 43 rd St & Oakesdale Ave SW, SW
