LJA provided preliminary and design phase engineering for the direct connectors from the Hardy Toll Road to the Grand Parkway/SH 99. The Hardy Toll Road provides a third controlled access route from the north Harris County/Montgomery County area into the heart of central Houston. Allowing high speed interchange for traffic on the Grand Parkway is a key feature in linking SH 99 into Houston via the Hardy Toll Road.
In order to meet the planned opening scheduled for SH 99, the interchange designs were prepared on a fast-track schedule and put out for bid within only seven months in early 2015 for $34 Million.
On top of a tight schedule, we realigned the north bound direct connectors to avoid potential impacts to the newly reconstructed facilities at Harris County’s Dennis Johnston Park. Additionally, great efforts were taken to avoid creating drainage issues or environmental impacts to areas in and around the construction.
