N. Going Street
Railroad viaduct
Project Background
The Going
Street Bridge serves as the link to the Swan Island industrial
area in North Portland. It was originally constructed in the
1930's and was widened in the 1970's. There have been no updates
to the bridge since the 1970's and it is in need of seismic
upgrades. Given the bridge's current structural condition, in a
moderate earthquake the Going Bridge would most likely collapse on
the railroad tracks below.
The City of
Portland has a prioritized list of city-owned bridges in need of
seismic retrofitting. The Going Street Bridge is identified as
one of the city’s top priorities for seismic upgrades. This
bridge is considered vulnerable to impact of a moderate seismic
event.
Seismic Retrofit
The N. Going
Street Seismic Retrofit Project will provide structural and
geotechnical engineering assessment and design to retrofit the
existing bridge structure to resist seismic loads. The design
shall conform to the latest ODOT seismic design criteria. This
criteria requires that the bridge remain serviceable after a
500-year return period event and that the bridge will satisfy a no
collapse criteria for a 1,000-year return period event. The
existing bridge still has an estimated 15-25 years of useable
life. It is anticipated that this seismic strengthening project
will prolong the life of the bridge up to 50 years.
There is $4,300,000 of funds
available for the design and construction of this project. This
total includes $3,000,000 of Oregon Transportation Investment Act
(OTIA) funds, $1, 000,000 of Federal funds and $300,000 of City
funds. City staff believes that if the seismic strengthening
can be done with little or no impact to the UPRR yard the cost of
this project will be reduced.
Bridge Replacement
To replace the
existing bridge with a new single column bridge is estimated to
cost $15,000,000 dollars. A new clear span bridge is estimated at
$20,000,000.
Waud Bluff Trail
The City of
Portland has received an ODOT (Oregon Dept. of Transportation)
Transportation Enhancement (TE) grant to construct the Waud Bluff
Trail. The route follows an existing "made path" down the
bluff just below the University of Portland to Swan Island. City
Parks will provide the required 10% match and has committed to
maintaining the facility. The trail will be paved, 10-12' wide
with a bridge over the UPRR track and stairs with bike slots (like
in Germany). At the top...Willamette Blvd will have a full
crosswalk and sidewalk piece to connect the trail to existing
sidewalks. At the bottom a full 12' trail will connect to Basin
Avenue. This will be a full 100%, 1st class facility that will
link two existing or planned regional trails, will provide much
improved access to Swan Island jobs and offer a walk/jog/bike loop
via Swan Island and Willamette Blvd for area residents and
employees.
The application
process for these grants was incredibly competitive, with projects
from all over the state in the running for a fairly small
pot...$7Million or so. Critical to our success was support from
Swan Island businesses, especially UPS, adidasAmerica and the U.S.
Coast Guard. Many individuals as well wrote cards and
letters in support of this project.
