They used to be able to drive to Wellington in about two hours and 20 minutes but now have to allow three hours.
"The roads are better but there's so much traffic now," Mr Hope said.
"I remember when we were buying fuel for about 48 cents a litre, then it went up to over $2. That's not easy for the trucking industry. There was a huge increase in road user charges and we suddenly had to find another $80,000 per year."
At one time they had seven trucks but that decreased to five after the global financial crisis. They kept their old Isuzu truck which has done 1.4 million kilometres and has never had any work done on its motor.
"We're getting a bit long in the tooth to try to build up the business again so decided it was time to sell," Mr Hope said.
The new owners, Mr and Mrs Hawkins, recently had a motel in Feilding but trucking was in Mr Hawkins' blood.
"I've been in transport most of my life and was looking at buying a big unit but I liked the idea of working for myself," Mr Hawkins said.
"I think Whanganui's taking off and have realised what gets built in this city that goes all over the country. I appreciate that Bryce and Kevin are passionate about the business and they have so much knowledge and experience so I hope they will stay on for a while."
Mr Hawkins will focus on trucking and Mrs Hawkins will look after administration. Mr Hawkins hopes that his sons may move into the business eventually.
Meanwhile, Mr Whibley and Mr Hope are looking forward to continuing to work together.
"We've had a good partnership - 30 years have gone bloody quick," Mr Whibley said.
