Loop 410 from Ingram Rd. to SH 151 and SH 151 from Loop 410
to Hunt Ln.
Status: Under construction (59% complete)
This $81.8 million project will construct the first phase of a
interchange at Loop 410 and SH 151. Specifically, this phase
the eastbound SH 151 to northbound Loop 410 and the southbound
Loop 410 to westbound SH 151 connectors. In
addition, Loop 410 will be widened to eight lanes from Ingram to SH 151
and auxilary lanes will be added to both directions of 151
Loop 410 to Potranco (eastbound) and Hunt (westbound.) Several
ramps on Loop 410 and SH 151 will be relocated to accomodate the new
connectors and to improve traffic flow. An access road
on southbound Loop 410 at Military will be added as will turnarounds on
at Ingram, Potranco, and Hunt.
project will help
This project will provide new direct connections on the
turn movements in the 410/151 interchange. This will remove
traffic from the existing intersections and access roads which will
overall mobility and safety for the remaining turning movements and local traffic. The addition of an extra lane
Loop 410 will help eliminate the bottleneck in that area. Since
the existing exit for SH 151 on southbound Loop 410 will be removed,
the access road flyover on southbound Loop 410 at Military will allow
traffic headed to eastbound SH 151 as well as accessing the commercial
areas at SH 151 and Loop 410 to bypass the signalized intersection at
Work started on October 10th, 2015, and is expected to be complete in
late 2018. Future projects to complete the full interchange are
not yet funded, so there is no timeline for those.
- Why did work stop for so long on the flyovers?
engineering error was discovered in the plans for the long steel beams
that will used in the missing section. This error was caught before
manufacture of those beams; however, it took some time to correct the
error. This delayed the manufacturing of those beams. In the meantime,
in order to prevent the project from being delayed, the
contractor worked on other areas of the project out-of-sequence.
