Florida State Road 694

The Gandy Freeway has been in planning books for decades, with a roughly 12.6 miles (20.3 km) stretch between a proposed connection to the Lee Roy Selmon Expressway in Tampa, and US 19 (or somewhere westward). Due to the low likelihood of the Hillsborough County portion being constructed, and increasing urbanization of Pinellas Park, the freeway was ultimately shelved (with portions west of US 19 being cancelled). Remains of the original freeway can be seen in the Gandy Boulevard interchange at I-275 (which lacks several ramps that were originally planned to be built), the separated grade diamond interchange at US 19 with Gandy Boulevard as limited access, and the very wide right-of-way preserved along Gandy Boulevard east of I-275.

Looking at the Gandy Freeway overpasses at 4th Street N, St. Petersburg, FL

After being shelved for decades, largely due to a lack of funding, the Gandy Freeway section from just east of 4th Street N to the I-275 interchange was finally built at a cost of $83 million. This project comprised a four to six-lane elevated highway, with overpasses at 4th Street N/Roosevelt Boulevard, 9th Street N (also known as MLK Street N), and 94th Avenue N. A four lane frontage road system (two lanes in each direction) would parallel the elevated structures.[4] In recent years, the Florida Department of Transportation has seen this particular project as an increasing priority for relieving congestion along the corridor, which is why the project was fast-tracked for construction in recent years.[5]

On December 14, 2016, the new eastbound elevated lanes opened over 94th Avenue N, with the westbound direction opening on February 12, 2017. The new westbound elevated lanes over MLK Street N, Roosevelt Boulevard, and 4th Street N opened on June 18, 2017, with the eastbound direction opening on June 23, 2017. As of February 1, 2018, both frontage roads were completed and fully operational.

The Gandy Boulevard interchange with I-275 is technically incomplete, lacking a free-flowing flyover from northbound I-275 to westbound Gandy. Originally, the interchange was also without a ramp from eastbound Gandy to southbound I-275 (this ramp was constructed in 1981). It is currently unclear if a free-flowing ramp will be constructed from northbound I-275 to westbound Gandy and there is speculation that this component of the project has been rolled into the controversial toll lane project formerly known as Tampa Bay Express.

Plans were also in the works to build an overpass at the intersection of Gandy Boulevard and Grand Ave, but those plans were cancelled due to community opposition.[6]

On Tuesday, January 6, 2015, a fuel tanker traveling westbound on Gandy Boulevard collided with a utility truck traveling southbound on Roosevelt Boulevard. Fuel from the tanker leaked and ignited, causing a huge fireball of flames to erupt. Fire crews from multiple departments; including Pinellas Park, Largo, Seminole, St. Petersburg and the St. Petersburg-Cleawater International Airport, responded to the incident, and it took well over an hour for the fire to be extinguished. Both drivers were transported to area hospitals; with the driver of the tanker truck suffering second and third-degree burns throughout most of his body. The driver of the utility truck suffered lacerations and fractures.

The severity of the incident has caused environmental concerns, as fuel seeped about four feet into the ground around and beneath the damaged roadway. Flames from the fire also charred the retaining wall that now carries westbound traffic over 4th Street and Roosevelt Boulevard. The Florida Department of Transportation evaluated the condition of the wall and determined that the affected section would need to be partially rebuilt. The work was able to be completed without significantly delaying the overall project.[7][8][9]
