The main objectives of the project are:
- to relieve the congested Silver Jubilee Bridge, thereby removing the constraint on local and regional development and better provide for local transport needs
- to apply minimum toll and road user charges to both the Mersey Gateway Bridge and the SJB consistent with the level required to satisfy the affordability constraints
- to improve accessibility in order to maximise local development and regional economic growth opportunities
- to improve local air quality and enhance the general urban environment
- to improve public transport links across the River Mersey
- to encourage the increased use of cycling and walking
- and to restore effective network resilience for road transport across the River Mersey.
