Yorkshire Water has completed work on the A65 almost two weeks earlier than originally planned.
The project to connect the new development on Skipton Road began on 27 July and was due to finish on 21 August.
Instead, it was completed over the weekend, with the road now fully reopened.
A Yorkshire Water spokesperson said:
"We know that our work has been disruptive over the last two weeks, and we really appreciate everyone’s patience and understanding.
"We’ve done our best to respond to complaints around the disruption by constantly manning the lights and changing the layout of the site, but mostly, by speeding up our work schedule so that were able to return things to normal much sooner than expected.”
Over the previous week, a second team from contract partners, Avove, joined the existing team to work on site simultaneously, and working hours were extended.
Yorkshire Water also accelerated reinstatement of the road and brought forward elements of testing and commissioning the pipework.
The new development has now been connected to both the water and wastewater network.
