Great Pacific TV has picked up more momentum from its Highway Thru Hell series. 

Bell Media’s Discovery announced Monday that production is currently underway on Great Pacific’s Heavy Rescue: 401, a new original docu-series based on Highway Thru Hell. The hour-long series will follow major tow truck operators, rescue and maintenance crew as they deal with problems on the stretch of the 401 spanning from Sarnia eastbound to Toronto and north to Barrie.

The number of episodes to be featured in the first season of the series has yet to be determined, a Bell Media spokesperson told Playback Daily. It is expected to go to air by 2017.

Great Pacific’s Highway Thru Hell currently ranks among the top five programs on Discovery, and among the top 10 programs on entertainment specialty TV to date, Bell Media said in a release. The series follows the Jamie Davis Heavy Rescue Team as it cleans up accidents on British Columbia’s Coquihalla Highway. The average audience for the fourth season of Highway Thru Hell, which aired on Tuesdays at 10 p.m., was 589,000 (P2+). Production is currently underway on the fifth season of Highway Thru Hell, Bell Media confirmed.

Heavy Rescue: 401 is produced by Great Pacific TV in association with Discovery Canada. Executive producer on the series is Mark Miller, with Todd Serotiuk serving as series producer. Great Pacific Media was acquired by Thunderbird in December 2014.
