President Donald Trump has announced the renovation of the Lincoln Memorial Reflecting Pool, which was built in 1922, is in poor condition and needs significant upgrades. The project will involve resurfacing the bottom of the pool using a coating similar to materials used in swimming pools to improve its appearance and durability. Initial bids were initially estimated at $300 million, but the renovation will take about three years. The work is expected to be completed before the nation's 250th anniversary celebrations.
