I-49 North, Segment K Bridge
The I-49N project involves the construction of a four-lane interstate from I-220 in Shreveport, Caddo Parish, Louisiana to the Arkansas state line. This I-49N Project is Segment K, a precast segmental bridge project (the first in the State of Louisiana) separated into 11 segments. The interstate provides a seamless link from Louisiana ports to the Arkansas border, significantly improving commercial shipping and cargo infrastructure, supporting Louisiana’s growing trade volume and economic development. SDI performed post-tensioning supply on this job, including over 8,700 segmental couplers specially designed by SDI’s engineering team to improve post-tensioning performance and installation speed. SDI is proud to have played a part in this great project (The I-49N Bridge is now recognized by ASBI as an award-winning new bridge).
