Six-phase corridor project from Main Street to the SH 114 access roads: dual turn lanes, median extensions, pavement markings and pedestrian crossings
Sofee’s read
Necessary maintenance. Southlake is investing to maintain quality.
$2M
2025–2026
Major work complete, finishing 2026
What could happen
If it goes well
Carroll Avenue improvements finished ahead of schedule. Traffic flows better at the intersections. The corridor looks polished, and Southlake maintains its 'everything is nice' reputation. Property values along the corridor stabilize or modestly improve.
Watch out for
The risk here was never the project failing -- at roughly $2M across six phases, it is maintenance, not a bet. The real watch-out is what it does not fix: turn lanes ease intersections, they do not add capacity. If Southlake's traffic grows, this corridor needs a bigger answer later.
What this means if you buy nearby
Main Corridor Upgrade: N. Carroll Avenue is Southlake's primary north-south corridor. This roughly $2M project added dual turn lanes, median extensions, pavement markings and pedestrian crossings across six phases between Main Street and the SH 114 access roads.
Traffic Relief: Carroll Avenue congestion has been a long-standing complaint. The work targets flow at the intersections rather than widening the road, so the corridor keeps its character.
Already Done: The city reported major work complete ahead of schedule in April 2026, with the remainder wrapping up through the year. If you're buying along Carroll Ave now, the disruption is behind you.
