TAMPA — If you frequently cross the Howard Frankland bridge to travel between Tampa and St. Petersburg, you may have noticed multiple lane markings in the last few months.

Some look faded and some appear new.

Driving along I-275 N you can clearly see the old lane markings and the new ones that were repainted just before exit 39, (the airport and Kennedy and Westshore Blvd. exit) at the end of the Howard Frankland bridge. This is a apart of the plan to widen the lanes to ease congestion. [MONIQUE WELCH | Tampa Bay Times]

Reader Paolo Sanchez noticed the weird lane shifts a couple of times now and asked about their purpose.

Well, the Doc is here to tell you that it’s for the best.

As the Doc’s colleague Caitlin Johnston previously reported, it’s all part of a two-year Interstate 275 construction plan to improve the Westshore area (northbound exit 39), which is known to have bumper-to-bumper traffic throughout the day at times.

“The main purpose of this project is to add a lane in each direction of I-275 to eliminate the current (congestion) that exists where traffic in the through-lanes has to merge from three to two lanes,” said John McShaffrey, the community outreach manager with the Florida Department of Transportation.

“A few other areas of I-275 and the ramps will also be widened to help improve traffic flow.”

The current lane shifts are part of the Department of Transportation's I-275 operational improvements project at the Westshore area to widen the road and add a through lane to eliminate the merge point where the congestion builds up.

The Department of Transportation had a contractor place the shifts on northbound and southbound I-275, and on the northbound exit ramp to State Road 60 to allow room for upcoming construction activities. They are also currently installing temporary barrier walls during nighttime operations to separate the work zones from the active travel lanes.

The construction zone spans 2.4 miles on I-275 from east of the Howard Frankland Bridge to east of Lois Avenue and you can expect lane closures from west of SR 60 (Exit 39) to Lois Avenue (Exit 40B) from 9 p.m. to 4 a.m. Friday through Saturday

The agency estimates the project will be completed by early 2021.
