Bridge Height Witham Bank East, Boston - Find a freedom of information request

Under the Freedom of Information act I would like to request the value of the height restriction (in meters or/and feet as per the sign in reality) for vehicles passing under the bridge on Witham Bank East, Boston (52.982209, -0.030179).

I would like to know what the sign says. I work for a mapping company which routes trucks. When we compare our map data with other source data we are getting different heights between different source data at this bridge. I would like to know what the sign states in reality. This will information be used to route trucks and avoid low bridges.

Lincolnshire County Council do not maintain the signs on this bridge because the road beneath the bridge is not public highway. Google map images, dated 2019, indicate the signed bridge height is 2.4m 8' 0". If more detailed measurements are required please contact Network Rail; asset owner of the bridge/structure.
