CSI delivered full conceptual-to-final design services for the Argyle Forest Boulevard Widening Project, a two-phase road expansion initiative on behalf of the Jacksonville Transportation Authority (JTA) in Jacksonville, Florida. Across both phases, the project transformed 4.6 miles of two-lane roadway into a modernized four-lane corridor, significantly improving traffic capacity, transit access, freight mobility, and multimodal connectivity in the rapidly growing Argyle Forest community of West Jacksonville.
Phase I
Argyle Forest Boulevard — Blanding Boulevard to Westport Road
2.6-Mile, 2-Lane to 4-Lane Roadway Widening
Phase I expanded Argyle Forest Boulevard from Blanding Boulevard to Westport Road — a corridor of approximately 2.6 miles — from a two-lane to a four-lane divided roadway. CSI managed the complete design process from conceptual planning through final construction documents.
Design services included:
Roadway widening design from 2-lane to 4-lane cross-section
Bridge design (AASHTO Type II) over McGirts Creek, including bridge hydraulics report
Gravity wall and MSE (Mechanically Stabilized Earth) retaining wall design
Concrete box culvert design and extension
Floodplain Compensation Facility (FPC) design to address stormwater and floodplain impacts
Environmental permitting through the St. Johns River Water Management District (SJRWMD) and U.S. Army Corps of Engineers (USACE)
Public involvement meetings with adjacent homeowners and community stakeholders
Eight (8) JTA bus pull-out designs to support Jacksonville Transportation Authority transit operations
Signing, pavement marking, traffic analysis and study, and traffic signalization design
Roadway lighting and landscape plan
Geotechnical investigation and analysis
Water, sewer, and underground electrical design coordinated through Jacksonville Electric Authority (JEA)
Environmental studies and detailed construction cost estimating
Phase II
Argyle Forest Boulevard — Westport Road to Bridge Creek Drive2.0-Mile, 2-Lane to 4-Lane Roadway Widening
Phase II continued the corridor expansion, extending Argyle Forest Boulevard from Westport Road to Bridge Creek Drive — an additional 2.0 miles — completing the four-lane build-out of this critical West Jacksonville arterial roadway.
Design services included:
Roadway widening design from 2-lane to 4-lane cross-section
Drainage design and concrete box culvert design and extension
Gravity wall and MSE retaining wall design
Environmental permitting through SJRWMD and USACE
Public involvement meetings with homeowners and neighborhood stakeholders
Eight (8) JTA bus pull-out designs supporting expanded transit service
Signing, pavement marking, traffic analysis and study, and traffic signalization design
Roadway lighting and landscape plan
Geotechnical services
Water, sewer, and underground electrical design coordinated through JEA
