Limited Access Design


Florida's Mainline Turnpike Widening  

Florida’s Mainline Turnpike Widening from Beulah to SR 50
Florida’s Turnpike Enterprise

This project involves widening 4.6 miles of the Mainline Turnpike from four-lanes to eight-lanes with a construction estimate of approximately $105 million dollars.  The limits of the project are from Beulah Road to SR 50 within the Central Florida community area.  This project was required to increase capacity for both the long distance travelers and local commuters who utilize this roadway.  This project also includes the reconstruction of the Turnpike and the SR 50 interchange.  The interchange will be converted from a partial diamond with a loop ramp to a full diamond interchange and also includes two new ramp toll plazas.  There are two new proposed bridges and widening of the existing bridges over SR 50, along with the design of noise walls along the corridor.  The purchase of right-of-way was minimized by using drainage swales and minimal pond sites.  Other design efforts included signing and marking, signals, lighting, landscaping, ITS and utilities.  DRMP provided roadway design, drainage, permitting, maintenance of traffic, paving, bridges, toll plazas, signing and marking, signalization, sound walls, surveying and right-of-way mapping services for this project.

SR 528 Beachline Widening  

SR 528 Beachline Widening
Florida's Turnpike Enterprise

SR 528 is part of the Florida's Turnpike Interstate System and an important connector between Interstate 4 and the Orlando International Airport.  DRMP provided design and permitting services to widen the roadway from four-lanes to six-lanes of eight miles of SR 528 from I-4 to McCoy Road.  The project evaluated widening to eight lanes and preparation of construction plans for six lanes.  Additional roadway work included adding new ramps and modifying existing ramps at the John Young Parkway Interchange, Interchanges at I-4, Orangewood Boulevard, International Drive, Consulate Drive and McCoy Road were resurfaced.  Drainage and environmental permitting was prepared for the ultimate eight-lane section.  Existing right-of-way was maintained by using existing interchange infield areas with the exception of three new ponds.  The existing Mainline Toll Plaza was redesigned to accommodate Express Toll Lanes.  There are 11 bridge sites (22 total bridges) to be widened or reconstructed.  Bridge overpass include going over existing local roads, Shingle Creek and existing CSX Railroad Tracks.  Additional structural design was required for the addition of noise walls adjacent to existing communities along the travel corridor.

Suncoast Parkway  

Suncoast Parkway 2, Section 1
Florida’s Turnpike Enterprise

This project involves the design for 8.9 miles of a new limited access roadway with a construction estimate of $150 million dollars.  The limits are from the end of the existing Suncoast at US 98 north of Tampa and ends just north of Cardinal Street.  This 8.9 mile section is one piece of a proposed 26 mile extension of the Suncoast Parkway for Florida’s Turnpike Enterprise.  This project includes five new bridge sites, one will be a proposed wildlife crossing and potentially new ramp toll plazas.  Other design efforts include drainage, signing and marking, signals, lighting and right-of-way mapping. The project goes through a portion of an existing Florida State forest.  Special emphasis has been placed on addressing environmental issues throughout the 26 mile corridor.  The DRMP team is also preparing a re-evaluation document which will update an approved 1998 State Environmental Impact Report (SEIR).  In addition, the DRMP team is leading the environmental work and permitting for the entire 26 mile corridor.

SR 417 Widening from SR 528 to Curry Ford Road
Central Florida Expressway Authority
Formerly Orlando-Orange County Expressway Authority

DRMP provided transportation engineering design for the widening of SR 417 from 4-lanes to 8-lanes from SR 528 to Curry Ford Road for approximately 3.34-miles in Orange County, Fla. This limited access facility has ramps serving two interchanges at Lee Vista Boulevard and Curry Ford Road.  The existing mainline toll plaza was re-aligned. The project required design for relocation and modification for existing drainage, signing and pavement markings and new roadway lighting. The bridge over Lee Vista Boulevard was widened to the median. Soundwalls were constructed along 0.8 miles of the east right-of-way line.  ITS design included the relocation of all existing fiber optic ductbanks, data collection sensors, cables, manholes, and pull boxes in areas where the existing locations conflicted with construction.

SR 429 (Western Beltway) Project 201
Central Florida Expressway Authority
Formerly Orlando-Orange County Expressway Authority

DRMP was responsible for the transportation engineering design for the extension of 2.8 miles of the Maitland Boulevard Expressway from CR 437 to north of SR 500 (US 441). The project involved the design of a new six-lane limited access facility with a new interchange at the SR 429 to provide access to US 441.  New concrete girder bridges were designed at Lust Road (79-feet long), Peterson Road (70-feet long), and General Electric Viaduct (881-feet long). New steel girder bridges were designed at CR 437/Binion Road (350-feet long) and US 441 (416-feet long). A stormwater conveyance system, drainage ponds, and environmental permitting were also designed and obtained.
