SUBJECT: Broadmoor Interchange Project DRAFT Phase 2B Scope of Work Project #21x06-725
SCOPE OF WORK
INTRODUCTION
The I-182/Broadmoor Boulevard interchange design project is intended to identify, recommend,
and design a solution that addresses the short and long-term interchange needs for all modes of
travel. The design for the I-182/Broadmoor Boulevard interchange project will consists of two
phases:
Phase 1: Access Revision Report (ARR) and Initial Environmental Permitting Process – Partially
Compete
Phase 2: Interchange Design – broken into multiple sub-phases (A & B)
Phase 1 of the project included the Access Revision Report, the design alternatives evaluation and
selection required by WSDOT and FHWA for a project that makes any access change to an
interstate interchange. The outcome of the ARR process is a “Preferred Alternative” conceptual
design, which is then approved by FHWA and WSDOT. The ARR documentation is complete, and
currently in the review and approval process with FHWA and WSDOT. In addition, Phase 1 of the
project included the Environmental Permitting process. The NEPA discipline reports are currently
underway based on the Preferred Alternative identified in the ARR.
This scope of work (titled Phase 2B) addresses the remaining tasks required to complete the full
design of the following components of the Preferred Alternative identified in Phase 1 of the project:
•I-182 Deceleration Lane at existing eastbound off-ramp to Broadmoor Blvd
•I-182 Eastbound Loop Ramp to northbound Broadmoor Boulevard
•I-182 Eastbound Ramp terminal New Roundabout
EXHIBIT A
BROADMOOR INTERCHANGE PROJECT PHASE 2B • SCOPE OF WORK • AUGUST 10, 2022 2
• Broadmoor Blvd re-striping to add a temporary bike/ped connection through the I-182
interchange
This scope of work also includes the preliminary engineering needed to complete the anticipated
NEPA Categorical Exclusion for the Preferred Alternative identified in Phase 1. The Preliminary
design elements included in this scope of work to complete the NEPA process includes the
following:
• New ped/bike bridge and path along Broadmoor Blvd through the I-182 interchange
PHYSICAL PROJECT LIMITS
For the purposes of this scope of work, the project limits are confined to the areas shown in Exhibit
1 as the preferred alternative from the Broadmoor Interchange ARR. The elements of the Preferred
Alternative shown in blue will be advanced through final design in the scope of work, and the
elements shown in green and yellow will be advanced through preliminary design to an extent
sufficient to support the complete of the NEPA documentation.
