The Hexham bypass appears to be due to open in 2026 , with multiple reports describing the Hexham Straight widening as due for completion that year. A February 2026 NSW release said the Hexham bottleneck was already complete, while other coverage says the broader Hexham Straight project is due in 2026.

What that means

  • The Hexham bottleneck widening is already finished and open to traffic.
  • The full Hexham Straight / bypass-style upgrade is reported as due in 2026 , but the sources I found do not give a precise day or month.
  • If you meant the nearby M1 extension to Raymond Terrace , that has been reported as expected in late 2026.

Practical takeaway

For a simple answer: it’s due sometime in 2026, with the exact opening date not clearly stated in the available updates.

TL;DR: Hexham’s main widening is already open, and the wider bypass- style project is expected in 2026, likely later in the year for the connected M1 extension.
