This is a pretty vague question - groynes are giant structures that can be built in a variety of places for a variety of reasons. Depending on ocean or river, cost of local labor and type of wood and whether you are attempting a complete barrier or a partial permeable one it's going to vary too much to give a concrete answer.

Oh, dude, wooden groynes can last anywhere from 25 to 50 years, depending on factors like maintenance, weather conditions, and how much they're being harassed by seagulls. But hey, don't stress too much about it, they'll probably outlast your favorite pair of jeans anyway.
A groyne is a hydraulic structure that is used to interrupt water flow and to keep sediment from moving. Groynes can cost up to $770,000.
The cost of a wooden groyne can vary significantly depending on factors such as size, materials, location, and labor. On average, the price can range from $5,000 to $20,000 per structure. However, larger projects or those requiring specialized materials may exceed this range. It's essential to consult with a local contractor for a more accurate estimate based on specific project requirements.
Wooden desks can be found for around $150.00 but these can be poorly manufactured and easily broken. A quality wooden desk can cost anywhere from $800.00 to as much as $3000.00.

The average lifespan of groynes typically ranges from 25 to 50 years, depending on various factors such as material used, environmental conditions, and maintenance practices. Wooden groynes may have a shorter lifespan due to decay, while those made of concrete or stone can last longer. Regular inspections and maintenance can significantly extend their effectiveness and durability.
