A major highway project under construction since 2013 will take a big step towards completion at 10 p.m. Friday night. The Dallas Horseshoe is the interchange on the south side of downtown where Interstates 30 and 35 meet. It is scheduled for completion this summer, but some key lane changes will be placed into their final alignment and available for drivers by Saturday morning.

The most significant change will be seen for drivers heading westbound on I-30 at Exit 46A. Currently, drivers headed south towards Waco would exit I-30 from the right hand lane. This setup may have led to confusion for some drivers expecting to naturally turn left to head southbound. The permanent placement taking effect Friday night will move the southbound exit to the two more conventional left hand lanes. The previously used ramp will now be an exit for Colorado Boulevard.
Once the shift happens, drivers can use entrance ramps from Canton and Harwood Streets to access westbound I-30 and both directions of I-35.
The Horseshoe Project is a $798 million redesign from the Texas Department of Transportation. The project website has a series of links and explanations for drivers.
