The Central Florida Expressway Authority (CFX) wants to hire a civil engineering firm to help design new bridges for the S.R. 528 and S.R. 436 interchange north of Orlando International Airport, and widening of S.R. 528 east of the airport, according to a Request for Letters of Interest (RFLI) issued on Tuesday.

Built in 1981 as a partial cloverleaf, the S.R. 528 (Beachline Expressway) and S.R. 436 (S. Semoran Boulevard) interchange serves as the primary access to the airport on its north side.


A direct connect flyover ramp from westbound S.R. 528 to the airport's access road (Jeff Fuqua Boulevard) was added in 2006, and since then the bridges of the initial interchange have begun showing signs of deck cracking during their regular inspections, according to a study completed earlier this month by Dewberry's Orlando office.

Insight into delays and extensions needed by both sides to appraise 1,162 acres south of Orlando International Airport for prospective sale to the developer.

Total replacement of the three 1981 bridges is now required, and CFX has decided to address deficiencies of the interchange area by eliminating the loop ramp from the airport's northbound exit to westbound S.R. 528, improving the angle of the eastbound off-ramp to northbound S.R. 436, adding an eastbound auxiliary lane between the S.R. 436 and Goldenrod Road interchanges, and widening S.R. 528 to at least six lanes.

Estimated construction cost for all the road and bridge improvements is more than $51.38 million.

Shortlist consideration will only be given to firms that have been pre-qualified by the Florida Department of Transportation to perform controlled access highway design and minor bridge design.

The engineering consultant would be tasked with final design and preparation of construction drawings for the proposed S.R 528 and S.R. 436 interchange improvements, and S.R. 528 widening.

Insight on the project's size and scope, and market factors motivating this national company to invest another $5 million in Orlando.

Specifically, the project calls for demolition of the existing bridges at the southbound S.R. 436 bridge over S.R. 528, the southbound S.R. 436 bridge over Ramp M, and the northbound S.R. 436 bridge over S.R. 528.

In addition, six new bridges will be installed: southbound S.R. 436 over S.R. 528, Ramp M over southbound S.R. 436, Ramp M over northbound S.R. 436, Ramp M over S.R. 528, northbound S.R. 436 and Ramp C-2 over S.R. 528.

A widening of S.R. 528 will provide six general use lanes through the interchange area, as well as an auxiliary lane eastbound to Goldenrod Road and potentially westbound to Conway Road.

Additional job elements include surveying, drainage evaluation and design, permitting, lighting, signing and pavement markings, maintenance of traffic, utility design and coordination, geotechnical analysis, scheduling and project control, progress reporting and other associated tasks.

The CFX evaulation committee will shortlist a minimum of three firms based on its scoring of the letters of interest and past performance on CFX projects, among other factors.

Learn who the prospective buyer is, how much they'll pay, and their vision going forward for this land that's been embroiled in bankruptcy for years.

The proposed improvements will be built in phases in order to maintain traffic on S.R. 528 and S.R. 436, and access to the airport at all times. Nightly road closures are likely for demolition of the existing bridges and construction of new ones.

Letters of interest are due by July 10 at 1:30 p.m.
