About this Project
The Florida Department of Transportation's (FDOT) contractor has completed widening the bridges and shoulders of Interstate 275 from south of Floribraska Avenue to north of Yukon Street.

This project widened shoulder areas to create a more consistent shoulder width (inside shoulders are typically about 21-feet wide; outside shoulders are 10-feet wide) for northbound and southbound I-275 to allow vehicles to pull all the way out of travel lanes for breakdowns and accidents. The major work involved the median (inside) shoulders. To accomplish this, partial demolition and widening took place on 13 pairs of bridges (for a total of 26 bridges). These bridges were widened to connect in the center and four of the bridges were also widened to the outside. There was also some widening on the roadway (non-bridge) shoulder portions of the highway.

The existing grass and guardrail in the median was replaced by a concrete barrier wall to tie into and match up with median conditions on the north and south ends outside the project limits. There was also some drainage, sign and signal work included in the project. Three overhead dynamic message signs (part of the Intelligent Transportation System network) were replaced by improved signs with color displays.

Traffic Flow
The construction phasing was designed so that all existing lanes of traffic and interchange ramps were open during peak traffic hours.

In order to maintain the construction schedule, and to minimize the impact to the traveling public, construction work and lane closures were done during nighttime hours.
