Two popular walking trails at the P.E.I. National Park at Dalvay are closed for the remainder of the year because of a major, $1.7-million infrastructure project.
A third waste water lagoon is being added to the Dalvay area.
Parks officials were concerned about the safety of walkers on the trails with the heavy equipment needed for the work.
The asset manager with Parks Canada on P.E.I., Bill Courtney, said the Woodlands Trail and Reeds and Rushes Trail are closed this year as a result.
"We have a waste water treatment facility in the vicinity of these two trails," said Courtney. "So there are two waste water lagoons and we are going to be adding a third lagoon and we are going to be adding aeration to all three lagoons as an upgrade."
"The problem we were having was capacity limitations. Our lagoons were filling quickly."
The project should be complete by the end of December.
