ORLANDO, Fla. — Heads up for those of you who drive Interstate 4 westbound and use two busy exits just south of downtown Orlando.

• Entrance ramp from John Young to I-4 westbound a bit longer
• Conroy Road ramp on I-4 westbound will come sooner

Starting Tuesday, if you are traveling from John Young Parkway onto westbound I-4, you will be on the entrance ramp a little bit longer before you join the interstate.

If you don't pay attention, you might just stay on Conroy Road instead of merging onto the interstate.

In fact, Conroy Road is also undergoing a big change Tuesday.

If you're on I-4 westbound, you'll have to make a decision sooner if you want to exit on to Conroy Road. That exit will now come a half-mile sooner.

Therefore, you should get over into the right lane sooner to exit and head toward the Mall at Millenia area.

The temporary ramp system will be used for a few months as "I-4 Ultimate" project construction crews work on the westbound lanes.

Crews are expanding this section of I-4 to 12 lanes of traffic; each direction will have four regular lanes and two express lanes.

Expect the existing ramps to close Monday night, and the new ramp to be up and running Tuesday morning.
