A consultation has been launched on the future of King's Dyke level crossing between Whittlesey and Peterborough.
There are around 10,500 trips over the crossing each day, with traffic being delayed by up to seven minutes at times.
The consultation starting on 30 October follows a feasibility study into different options, which was completed last year.
Cambridgeshire County Council are asking A605 users for their views on three possible alternative routes including bridges over the railway line, and in one case, a short bypass.
Details of the proposals are available in November's edition of the Discovering Whittlesey magazine as well as Cambridgeshire County Council's website. Project officers will be available to answer questions about the scheme at public exhibitions in both Whittlesey and Peterborough. These will take place on:
* 6 November 3pm "“ 7.30 pm, St John Ambulance, 2 Plough Road, Whittlesey, PE7 1LT
* 18 November 5pm "“ 7 pm, Tesco Express, 110 Whittlesey Road, Stanground, Peterborough, PE2 8RJ
* 26 November 4pm "“ 7.30 pm, Sir Harry Smith Community College, Eastrea Road, Whittlesey, PE7 1XB.
Cambridgeshire County Councillor Martin Curtis said: "The possible replacement of the level crossing has been long awaited around Whittlesey and beyond. I urge everyone to return the questionnaire in the Whittlesey Magazine or go online to fill it in and have their say on the bridge alternatives."
Project Manager Alistair Frost said: "We're keen to find out people's opinions on alternatives to the level crossing so that we can provide a solution which works for local residents and businesses."
More information on the scheme including visualisations, a map and online questionnaire are available at www.cambridgeshire.gov.uk/kingsdykecross. The consultation runs until the 15 December 2014.
