Work Detail

Architectural, Construction, Engineering And Inspection Services – Tnw_Ing_Landkreis Donau-Ries_Don 39 Clearance Of The Staudheim Level Crossing - New Construction Of A Road Overpass. The Donau-Ries District Intends To Clear The Level Of The Level Crossing West Of Staudheim By Building A New Crossing Structure At The Intersection Of Railway Line 5381 Ingolstadt-Neuoffingen With The District Road Don 39. The Measure Is Necessary Due To The Outdated Level Crossing Protection That Requires Replacement And The Increased Risk Of Accidents At The Level Crossing. Location And Inventory The Single-Track, Electrified Railway Line 5381 Crosses The District Road Don 39 At Railway Km 37+916.45 At The Same Level, With A Permissible Speed Of 120 Km/H On The Rails And A Gradually Reduced Speed On The Road Of 70 Km/H With A Subsequent Reduction To 50 Km/H In The Intersection Area. After The Crossing, The Speed Limit Is Lifted. The District Road Don 39 Has A Lane Width Of Only 6.40 M In The Area Of ​​The Level Crossing And Is Therefore Undersized For The Current Traffic Volume Of 3,035 Vehicles Per Day (2021 Census). In Addition, The District Road Is A Designated Diversion Route For The Parallel Federal Road B16. Due To Availability Restrictions On The B16, Up To 7,800 Vehicles And 2,000 Trucks Are Rerouted Via The Don 39 And Thus Via The Railway Crossing Every Day. Variant Investigation And Preferred Solution As Part Of The Preliminary Planning, Three Variants For Height Clearance Were Examined: - V07 - New Road Overpass: Raising The District Road On A Road Embankment Up To 7 M High Over The Railway Line - V08 - New Railway Overpass As A Prestressed Concrete Deck Bridge: Lowering The District Road By Approx. 9.00 M Below The Railway Line - V09 - New Railway Overpass As A Steel Trough Bridge: Lowering The District Road By Approx. 6.05 M Below The Railway Line After Weighing Up All Concerns, The Client Decided On Variant V07 - New Road Overpass As The Preferred Solution. Raising The District Road On A Road Embankment Over The Railway Line Is The Most Economical Solution And Does Not Trigger Any Interference With The Groundwater Body Description Of The Preferred Variant The Road Overpass Is Planned At Railway Km 37+985 As A Single-Span Reinforced Concrete Frame Ceiling With A Clear Width Of 7.70 M And A Clear Height Of At Least 5.70 M Above The Track. The District Road Don 39 Is To Be Realigned Over A Length Of Approx. 770 M And Raised Above The Railway Line. The Bridge Structure Is To Be Built Without Significant Interference With Ongoing Railway Operations. The Existing Level Crossing In Railway Km 37+916.45 Including The Outdated Safety Technology And The Concrete Switch House Must Be Completely Dismantled. Environment And Noise Protection The Project Is Subject To An Environmental Impact Study In Accordance With The Uvpg. No Significant Adverse Environmental Effects Are To Be Expected With The Preferred Variant. Costs And Financing The Total Costs Of The Preferred Variant V07 Are Expected To Be Eur 6.4 Million Gross. The Costs Are Entirely Due To The Crossing And Are Covered By D
