Project Updates
42nd Ave S Bridge Replacement: The City plans to open the 42nd Ave S Bridge to one lane
southbound traffic after review of the completed structural analysis and bridge inspection
report. The plan is to open the bridge to one lane in the southbound direction to allow 3
exits out of the Allentown Neighborhood. It is estimated that the bridge will open by April
1, 2022.
Design for the 42nd Ave S Bridge Replacement continues and is on schedule to have 30%
plans and engineering estimate in early to mid-2022. The draft type, size, and location
(TS&L) has been submitted to the City and has been presented to the Council at the
February 14 Committee of the Whole meeting. The Washington State Legislature passed
the $17 billion Move Ahead WA transportation package, which included $17 million for the
replacement of the 42nd Avenue Bridge. The City of Tukwila has also received funding
from PSRC and the State Local Bridge program, totaling an additional $14 million.
According to current engineering estimates, the City now has enough funds to complete
the 42nd Avenue Bridge replacement.
Project staff conducted a monthly Allentown meeting at the Tukwila Community Center
on February 22 to present the latest findings to the community and receive the initial
feedback. Staff continues to compile all the questions/comments to address the concerns
of the attendees. Council will continue to have the opportunity to review the draft TS&L
and ask any additional questions. Staff will present answers to the Council questions at
the March 21 Transportation and Infrastructure Services Committee meeting. Bridge
location selection by Council is planned for the March 28 Committee of the Whole

Re: 42 Ave S Bridge Re-Opening Following Critical Damage Repair
nd
Ave S Bridge was subject to a high impact load from a truck on
Wednesday 12/15. The truck struck one sway frame of the bridge and inflicted some critical damages to
the mentioned sway frame and its associated vertical elements of the through-trusses of the bridge.
The bridge was closed shortly after this incidence by City Police Department and on Thursday 12/16,
the King County inspection crew performed an in-depth inspection of the damaged areas.
Since that time, the bridge has been repaired by a City-hired specialty contractor and been post-repair
rd
inspected by the King County bridge inspection crew. Furthermore, on January 3
team performed additional non-destructive testing on a critical gusset plate on the bridge under City
supervision.
The results of post-repair analyses show that the bridge is further compromised due to this impact, and it
can only serve a one-way traffic safely.
It is the recommendation of the WSDOT Bridge Engineer, King County Inspectors, TranTech Engineers
nd
and City staff that the City reopens the 42 Avenue bridge to one-way traffic until the bridge can be
replaced. For this reason, City haudy traffic attributes of both north-
bound (NB) and south-bound (SB) one-way traffic alternatives on the bridge.
The following presents a summary of this comparison study:
NB alternative would require Allentown traffic to exit via S 115th St or S 129th St only. The S
115th St/E Marginal intersection is unsignalized which may make outbound left turns
challenging and result in queuing back on S 115th St. SB alternative provides Allentown with 3
exit locations; two of these locations are signalized which can better facilitate the outbound
turning movements.
Given the load limits on 42nd (north of 124th), the SB alternative allows two different routes out
of Allentown for trucks. With NB alternative, trucks would only be able to exit via 129th to
MLK Way. If for any reason 129th is impacted and/or needs to be closed, trucks would
essentially be stranded in Allentown. The SB alternative mitigates this issue by providing
redundancy.

The SB alternative allows trucks to avoid the steep climbing grade on 129th during inclement
weather. Trucks may have challenges in the opposite downgrade direction during inclement
weather as well, but this should be more manageable than the upgrade.
The NB alternative requires fewer needed temp channelization/ signal modifications than the SB
alternative.
Regarding Emergency Fire access, SB alternative provides for better egress for Fire Station 53
response. This is the established SB response route for Station 53.
SB alternative provides less truck impacts to the Superette corner store parking and its patrons, it
nd
reduces traffic on 42 Avenue heading NB in the neighborhood and restores some normal traffic
th
flow in Allentown with less cut through traffic via S. 116.
In comparing and analyzing the mentioned attributes of the NB and SB one-way travel alternatives over
ecommend the SB travel alternative for the bridge re-opening.

Memorandum
To: Public Works Department, City of Tukwila
From: KPG Psomas
Date: 3/8/2022
Re: Transportation Analysis for the 42nd Avenue S Bridge Reopening
In December 2021, the 42nd Avenue S bridge over the Duwamish River was damaged by an
overheight truck load and was closed to all modes of travel. The City has been working on repairs
to reopen the bridge. Due to the condition of the bridge, it can only be opened with a single lane
of traffic. This memorandum evaluates the advantages and disadvantages of operating the bridge
with one northbound lane versus one southbound lane and provides our recommendation.
Allentown Neighborhood
The 42nd Avenue S bridge over the Duwamish River connects Interurban Avenue S with the
Allentown Neighborhood. The approximate boundaries of the Allentown Neighborhood are the
Duwamish River to the south and west, S 115th Street to the north, and I-5 to the east. The
primary land uses in the Neighborhood are residential, Tukwila Community Center, and the BNSF
Railway Intermodal facility. Fire Station 53 is located in the Neighborhood at 4202 S 115th Street.
There are three access points to the Neighborhood: S 115th Street, the 42nd Avenue S Bridge over
the Duwamish River, and S 129th Street bridge over I-5 that connects to Martin Luther King Way S
(SR 900).
The City has reached out and solicited feedback from the Allentown Neighborhood residents
regarding whether to reopen the bridge in the northbound or southbound direction. Feedback
from the neighborhood is a preference to open the bridge in the northbound direction. Residents
have expressed concern about trucks traveling downhill (westbound) on the S 129th Street bridge
over I-5. There were no reported crashes of this type at this location from January 2016 to
September 2021.
Transportation Analysis
This section evaluates the trade-offs of reopening the bridge in either the northbound or
southbound direction.
Single Lane Northbound Traffic
A northbound bridge would provide three entry locations (S 115th Street, S 129th Street and 42nd
Avenue S) and two exit locations (S 115th Street and S 129th Street) for the Allentown
Neighborhood.

Pros
Provides more direct access to enter the Neighborhood from locations to the south.
Trucks and other vehicles entering the Neighborhood have good access from both
northbound and southbound I-5.
Cons
More difficult for trucks and other vehicles to exit the Neighborhood to access southbound
I-5. There are no I-5 southbound on-ramps at the I-5/S Boeing Access Road interchange.
Vehicles would need to travel northbound on 42nd Avenue S to S 115th Street and then
southbound on Interurban Avenue to access the southbound I-5 at S 133rd Street.
A third street entering the Allentown Neighborhood is expected to increase traffic volumes
using Neighborhood streets.
Single Lane Southbound Traffic
A southbound bridge would provide two entry locations (S 115th Street and 50th Place S) and
three exit locations (S 115th Street, 42nd Avenue S and 50th Place S) for the Allentown
Neighborhood.
Pros
Expected to reduce northbound truck traffic on the segment of 42nd Avenue S, north of
S 124th Street, which is signed for only local trucks serving local businesses.
Reduces the number of vehicles making unsignalized left turns from westbound S 115th
Street to southbound East Marginal Way.
Trucks and other vehicles exiting the Neighborhood would have simple access to both
northbound I-5 via Interurban Avenue S and southbound I-5 via S 133rd Street.
Provides trucks another route to exit the Neighborhood that does not require them to use
the steep uphill on the S 129th Street bridge over I-5.
Cons
Trucks traveling from northbound I-5 do not have a good route to enter the Neighborhood
and will be more likely to travel using eastbound on S 115th Street and southbound on
42nd Avenue S.
Recommendation
Based on the analysis above, feedback from the neighborhood and discussions with City staff, our
recommendation is to reopen the 42nd Avenue S bridge in the southbound direction. Reopening in
the southbound direction will provide more benefit to Neighborhood circulation and lower vehicle
traffic in the Neighborhood.
