SUBJECT: T91 Trail Bridge Removal and Segment Widening (CIP# C801192)
Amount of this request:
$1,475,000
Total requested project cost:
$1,525,000
ACTION REQUESTED
Request Commission authorization for the Executive Director to proceed with design and
construction for the T91 Trail Bridge Removal and Segment Widening. This single authorization
is for $1,475,000 of a total estimated project cost of $1,525,000.
EXECUTIVE SUMMARY
This project will remove the existing pedestrian/bicycle bridge and replace with an on-grade path,
widen the existing pinch point south of the pedestrian/bicycle bridge and upgrade the existing
rail crossing.
JUSTIFICATION
1) Improve Public Safety - This project improves public safety by upgrading these trail
segments to American Association of Highway and Transportation Officials (AASHTO)
design standards where applicable to allow for two-way traffic and reduce risk of
collisions.
2) Improve Accessibility - This project addresses accessibility challenges at the
pedestrian/bicycle bridge and the rail crossing to expand the number of users who can
enjoy and utilize this unique non-vehicular route between Interbay and Downtown.
Diversity in Contracting
Design is being executed through an existing IDIQ with preestablished contracting goals of 25%.
With the small nature of this project, it presents a great opportunity to have high WMBE

participation. The Diversity in Contracting Department will be engaged as part of the Bid
Document preparation to establish these goals.
DETAILS
Scope of Work
Work included to widen the two trail segments, about 750 feet of trail in total.
(1) Remove the existing pedestrian/bicycle bridge and replace with an on-grade path to
meet standard design criteria of a ten-foot paved trail (10’-0”) with two-foot (2’-0”)
buffers areas consistent with existing tree planting wherever possible.
(2) Widen the existing pinch point south of the pedestrian/bicycle bridge to a paved width
of 8-feet 6-inches (8’-6”) with no buffer by moving the east fence per an easement with
BNSF railroad. This is an acceptable alternate when existing fixed elements like train
tracks and buildings exist.
(3) Upgrade the rail crossing in the south pinch point segment to AASHTO or National
Association of Transportation Officials (NACTO) design standards address safety and
accessibility issues, which ever is the higher standard.
(4) Revise grading to direct flow to existing stormwater conveyance system. Coat new and
existing fences within the project boundary to reduce zinc runoff.
(5) Install new fencing where required and paint existing fence in segment areas to remain.
(6) Install conduit sleeves under the trail for future lighting opportunities.

ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternative 1 – Maintain the current condition.
Cost Implications: None.
Pros:
(1) No additional cost to the Port.
(2) No trail closure during construction.
Cons:
(1) Existing safety issues remain which could present the Port with potential Liabilities.
(2) Existing accessibility issues remain which limit usability and access to some users.
This is not the recommended alternative.
Alternative 2 – In addition to the proposed alternative, move the west fence three feet six inches
(3’-6”) at the southern pinch point to achieve a full 10-foot (10’-0”) paved width with 2-foot
(2’-0”) buffers on each side.
Cost Implications: $4,000,000 - $7,000,000
Pros:
(1) Trail segments will meet minimum design standards to the full extent, including at the
southern pinch point.
Cons:
(1) The rail spur would need to be shifted which would add considerable cost, extend the
construction duration, and cut off all rail access to the Port during construction.
This is not the recommended alternative.
Alternative 3 – Remove the existing pedestrian/bicycle bridge and replace with an on-grade path
meeting minimum design standards and widen the existing pinch point south of the
pedestrian/bicycle bridge as much as feasible per an easement with BNSF Railways.
Cost Implications: $1,525,000
Pros:
(1) Improves safety and accessibility.
(2) Limited project scope will facilitate a shorter construction period and impact to daily
users from the trail closure.
Cons:
(1) Due to the existing constraints of the existing rail lines on both sides of the trail, the full
standards design width with buffers cannot be achieved at the southern pinch point and
therefore tree planting is limited.
(2) Does not include time-intensive sustainability and equity elements, lighting installation,
or waste receptacles.
This is the recommended alternative.
