Alignment Study
Project Description
	Marigold Avenue - two-lane undivided roadway from south of Palmetto Street transitioning to a four-lane divided roadway approaching Cypress Pkwy. (approximately 2.2 miles)
	Cypress Parkway - two-lane undivided roadway from west of Solivita Blvd. transitioning to a four-lane divided roadway approaching Poinciana Medical Center (approximately 1.9 miles)
	Both existing roadways classified as Urban Collectors
	Land use is mostly residential blended with commercial
	Alignment study developed and evaluated alternative roadway alignments to recommend a preferred alignment and prepare plans for widening Marigold Avenue and Cypress Pkwy. (CR 580)
	Only considered Rural typical cross section for Cypress Pkwy.
	Typical Cross Sections analyzed for Marigold Avenue:
Urban
Suburban
Rural

Project Need
	Identified in Polk County Comprehensive Plan (Transportation Element)
	Polk TPO 2040 LRTP identifies widening as a need
	Future Southport Connector will add broader road network connectivity
	Traffic Study identified need for a 4-lane roadway and intersection improvements
	Crash data indicates safety issues along the corridors

Typical Cross Section Alternatives
Marigold Avenue:
 Existing: Two-lane rural roadway within 150' of right-of-way

 Studied: Urban, Suburban, and Rural 4-Lane Typical Cross Sections with three Alternative Alignments (left, center and right of the current roadway)
 Recommend: Urban 4-Lane Typical Cross Section on a center alignment with stormwater retention system, bike lanes, 6' wide concrete sidewalk and 12' wide asphalt multi-use trail

Marigold Avenue and CR 580 Alignment Study

Cypress Parkway:
 Existing: Two-lane roadway transitioning to a four-lane rural roadway within 300' of right-of-way
 Studied: Due to width of existing right-of-way, only one alternative was evaluated
 Recommend: Rural 4-lane Typical Cross Section on a center alignment with open drainage (swale) system, 5' wide paved shoulders, 5' wide concrete sidewalks, and 12' wide asphalt
