A programme of archaeological observation, investigation and recording was undertaken by Humber Field Archaeology during groundwork associated with a road diversion at Spurn Peninsula Roadway, East Riding of Yorkshire. Monitoring of the deepest excavation at the site, which constituted a new water services trench, revealed a sequence of mixed windblown and waterlain sands with occasional to moderate small gravel content. In one instance, a small patch of the underlying, modern mud flat was present towards the northern extent of the trench. No archaeological horizons, deposits or features were recorded within the monitored excavation and no artefacts were collected or retained.
