Work has begun on the £34m redevelopment of derelict land near Gloucester's railway station.
The railway triangle will be see a new business park, restaurant and pub, takeaways and a supermarket.
Gloucester City Council approved the proposals in 2011 after the area had been derelict for 20 years. Previous schemes such as a rugby stadium failed.
Gloucester Conservative MP Richard Graham said the development should "transform a gateway into Gloucester".
"People will look back and think 'that's significantly better than it was'," he said.
The first phase of work costing about £8m will see a new Morrisons supermarket and access road built, which will provide the infrastructure for the rest of the park.
