In September, NorthGate Construction crews completed the first demolition phase of the southbound SH 121 off-ramp to eastbound I-635. The remaining demolition work will take place in early 2020.  Crews have been switching traffic onto new pavement on northbound FM 2499 at I-635/SH 121 and the northbound FM 2499 frontage road at the corner of Cracker Barrel. This month, crews will switch traffic on the northbound SH 121 frontage road near Fellowship Church where traffic will be moved onto new pavement. Crews will also switch traffic at the southbound SH 121 frontage road off-ramp to the Dallas/Fort Worth International Airport. No bridge demolitions are scheduled for this month.
