There are two bridges across the Tay at Grandtully, the old bridge which is barely serviceable to vehicles and the new bridge a little further downstream.
The Old Grandtully Bridge is a narrow, single track structure with a 3T weight limit, and sharp turns at both ends. With so many problems, it is not surprising that the bridge was replaced over 30 years ago. The new concrete deck bridge lies almost a mile further downstream, and solves most of the problems that the old structure has, with one exception. Traffic still needs to make a right-angled turn to access the bridge at the south western bank. This manouvere is eased somewhat by the fact that the A827 also TOTSOs with the B898 here, so forcing traffic to slow down!
