TxDOT will demolish the ramp that thousands of drivers use on a regular basis to navigate downtown, and build a new one.
The current I-69/288 southbound ramp exits to the left from the northbound lanes of the Gulf Freeway, which has long-plagued the interchange with weaving drivers who slow traffic and cause wrecks.
TxDOT says when the new ramp opens in early July, drivers will be able make a decision much farther back to exit to the right.
TxDOT says this should reduce congestion through the area, which includes the University of Houston campus.
During the six-month closure, TxDOT is recommending drivers on that corridor travel north on I-45 through downtown, exit east on I-10, then take I-69 southbound.
See the maps below for more on the detours.
