LIMITED ACCESS DESIGN

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.

The project consisted to one of the first SUNPASS Only interchanges to be constructed on the SR 91 (Florida’s Turnpike) system.  The project involved building a new interchange at Milepost 107 and contained one of the first SUNPASS Only interchanges to be constructed on the Florida’s Turnpike System.  The project was designed and constructed within an area of environmentally sensitive wetlands and highly valued residential property.  The Toll Plaza was built under a separate contract (concurrent construction).  DRMP was responsible for nearly all aspects of design, except for the geotechnical design and Traffic Control Plans.  DRMP also prepared permit applications to the Water Management District and Department of Environmental Protection.

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.

The proposed SR 408 improvements provide for major reconstruction of this critical expressway facility from Conway Road to Oxalis Drive.  In addition to widening SR 408 from six to eight basic travel lanes, this project includes auxiliary lanes, replacement of the existing PCC pavement with asphalt pavement, and modifications to the SR 436 Interchange. A significant feature of this project is the implementation of express/open lane tolling operation, which allows customers with transponders to completely bypass toll plazas thereby improving capacity and operations.  Cash customers without transponders will continue to use separate toll plazas.  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 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.
