But now only vegetation on the opposite banks of the lake can be seen over the 80m section of cycleway where a narrow verge prevented continuation of the concrete pathway.
The couple believe the blocked view will hurt the value of their property.
"We think it's pretty awful. We support it going through; however, what we're upset about is that our views are going."
The trust was established in August 2010 to spearhead the 70km riverside cycleway from Ngaruawahia through Hamilton and Cambridge to Lake Karapiro and Horahora.
Waddell said he sympathised with the couple's concerns but when the trustees found out about the situation "they put the brakes on it" and looked at what they could do but couldn't resolve the issue.
They felt they did everything they could. He said unfortunately it wasn't the couple's land and the cycleway was for the whole community to enjoy.
"It's community money and we are responsible for that."
Trustee Simon Perry said it was disappointing to upset even one resident.
"But the reality here is we're fully funding this section of the cycleway and we're not asking for any ratepayer funding and there's a limit to what we can fund in terms of improvements to satisfy individual members of the community."
Project general manager Jennifer Palmer said the trust halted construction for three weeks to sort out the issue, and had construction company Livingstone Builders source a quote for a glass balustrade, but this was also declined by the couple.
"It's important to remember that we have to make the cycleway as safe as possible."
Ms Palmer said it was safer to have that section slightly above ground to give cyclists added protection from traffic and prevent people parking on it.
The 2km Karapiro section cost $2 million to build and funding came from community grants.
The ride is not part of the country's 19 cycle trails set up by the Government.
