Structure Ref. No 57

Name of Project Lynton and Barnstaple Railway

Name of Bridge or Structure Rowley Cross Railway Bridge

Structure Ref. No. LBR 57 OS grid reference SS 662 451 (266207 145050)

1 HIGHWAY DETAILS

1.1 Type of highway – unclassified road near junction of Minniemoor Lane and Leys Lane

1.2 Permitted traffic speed - 60mph (actual traffic speed is likely to be less due toproximity of junction with A39)

1.3 Existing weight restriction - none

2 SITE DETAILS

2.1 Obstacles crossed – single track of narrow gauge railway

3 PROPOSED STRUCTURE

3.1 Description of structure and design working life – masonry arch, 120 years

3.2 Structural type – masonry arch. The original arch is believed to have remained in-situbelow road level when the railway was abandoned and the approach cuttings infilled.The existence of the arch and its condition will be proven when excavationcommences, and any repairs such as repointing and re-waterproofing will be carriedout at that time. The condition of the foundations will also be confirmed. A loadassessment of the existing arch will be a carried out to BA 16/97, initially using MEXEanalysis followed by other methods if necessary. Strengthening of the original arch willbe carried out if needed to attain 40t vehicle loading. To give improved sight lines forhighway users turning to or from Minniemoor Lane, the arch will be extendedapproximately 2.787m westwards (centreline measurement) on a skew of 7.5° relativeto the road centreline, with a new masonry parapet constructed to match the existingeast parapet wall.

3.3 Foundation type – spread footings on bank seats

3.4 Span arrangements – single span 9.385m skew (8.534m square) measured betweenthe abutment faces. The crown of the arch is 6.477m above rail level. The structuregauge used is that of the Ffestiniog Railway, North Wales, due to commonality in thedimensions of rolling stock, which will be shared between the two railways. This haspreviously been accepted by ORR (formerly HMRI) thus setting a precedent. Thewidth of the structure is increased to allow for end throw and centre throw of rollingstock in accordance with curve geometry. See diagram ref. PW29J.

3.5 Articulation arrangements – abutments, arch, spandrels and parapets all integral instone and/or brick masonry, keyed into the existing masonry arch

3.6 Classes and levels

3.6.1 Consequence class – CC2

3.6.2 Reliability class – RC2

3.6.3 Inspection level – DSL2

3.7 Road restraint systems requirements – masonry parapets compliant with TD 19/06

and BS 6779: Part 4:1991. Metal safety fences will be used on the approaches to theends of the parapets.

3.8 Proposed arrangements for future maintenance and inspection

3.8.1 Traffic management – no effect upon highway traffic

3.8.2 Arrangements for future maintenance and inspection of structure. Accessarrangements to structure - underneath inspection conducted from scaffoldingor rail mounted vehicles when there are no trains running

3.9 Environment and sustainability – the masonry arch extension and parapet will beconstructed from locally sourced inert materials such as stone or brick with minimalenvironmental impact. No maintenance painting will be required. The use of recycledaggregates for backfill will be considered subject to meeting required qualityrequirements.

3.10 Durability, materials and finishes

4 Local stone and/or bricks class A engineering HD, F2, S2 to BS EN 771-1 and HighwaysAgency specification clause 2417, Table 24/4.

5 Cementitious mortar with added lime will be used; designation (ii) to Highways Agencyspecification Tables 24/1 and 24/6

6 Mass concrete C20/25 backfill to arch attaining 25N/mm2 cube strength at 28 days.Alternatively, foamed concrete may be used, subject to suitability.

7 Backfill to structure: granular material class 6N used above arch springing level. Note that inthe likely event of hard rock being encountered, a minimum width will be excavated for theconstruction of the abutment and the space behind backfilled with mass concrete.

8 Spray applied bridge deck waterproofing will be applied over the top of the extrados. Theremaining buried surfaces of the structure will be protected with two coats of cut back bitumenwaterproofing to within 0.3m of finished ground level in accordance with HA specificationseries 2000 and CIRIA C543 diagrams 3.5.3-2, 3.5.3-3.

9 Drainage will be provided at the back of the spandrels by means of a 150mm diameter filterdrain laid to 1 in 150.

9.1 Risks and hazards considered for design, execution, maintenance and demolition.Consultation with and/or agreement from CDM coordinator

10 Difficulty of extending foundations for the new bridge next to the existing bridge while retainingthe latter open to traffic.

11 Contaminated materials used to backfill the former railway trackbed and cutting exposedduring excavation

12 Uncharted utilities

13 Traffic hazards during construction. The highway will be kept open during construction of theworks requiring propping of excavations to ensure full support to the edge of the highway withfull live load surcharge allowed for. Temporary vehicle restraint barriers and demarcationfences will be provided to prevent vehicles and people entering deep excavations alongside ornear the edge of the highway.

14 No unusual hazards are anticipated during maintenance or subsequent demolition

2Printed 03/12/2015



14.1 Estimated cost of proposed structure together with other structural forms considered(including where appropriate proprietary manufactured structure), and the reasons fortheir rejection (including comparative whole life costs with dates of estimates) – archstructure is considered most suitable solution for whole life durability and lowmaintenance requirement, while replicating the heritage of the railway.

14.2 Proposed arrangements for construction

14.2.1 Construction of structure – the cutting will be fully excavated back to itsoriginal profile. The cutting sides will be cut back and prepared to receivebank seat abutment extensions to the existing abutments. Erect centring andbuild arch, keyed and/or dowelled into face of existing arch. The new arch willhave an identical profile to the existing. Build new parapet on the west side.

14.2.2 Traffic management – one lane working with traffic lights will enable a safetyzone to be maintained on the west side of the bridge

14.2.3 Service diversions – unknown, but a full utility search will be conducted beforedetail design and provision made for diversions if necessary.

14.2.4 Interface with existing structures – the arch extension and new westernparapet will be identical in profile and appearance to the existing arch andeast parapet.

15 DESIGN CRITERIA

15.1 Actions

15.1.1 Permanent actions – dead weight, horizontal ground pressure, surcharge andbackfill to PD 6694-1

15.1.2 Snow, wind and thermal actions – none

15.1.3 Actions relating to normal traffic under AW regulations and C&U regulations –LM1 and LM2. In all cases wheel loads are dispersed at 30° to the vertical tothe top of the arch, the buried depth is approximately 0.6m. Surcharge affectsare applied in accordance with PD 6694-1.

15.1.4 Actions relating to General Order Traffic under STGO regulations - LM3 SV80as defined in NA to BS EN 1991-2:2003 NA 2.16 (up to six 130kN axles at1.2m pitch in one lane only). SV80 minimum required to BD 91/04 Table 3.1.

15.1.5 Footway or footbridge variable actions – no specific provision since the wholelength of the arch will be constructed with the same section capable ofcarrying highway traffic over its full length

15.1.6 Actions relating to Special Order Traffic, provision for exceptional abnormalindivisible loads including location of vehicle track on deck cross-section –none

15.1.7 Accidental actions - the concrete parapet and its connection to the structurewill be designed to resist accidental impact from errant vehicles in accordancewith TD 19/06 and BS 6779 part 2. A yielding or frangible connection will beprovided between the parapet wall and the arch/spandrel structure to enableaccidental damage to be readily repaired without impairment to thesubstructure. The wing walls will be proportioned to have sufficient mass to beable to resist overturning and sliding effects.

3Printed 03/12/2015



15.1.8 Actions during construction – the spandrel walls will be designed toaccommodate lateral pressure from vibratory earth compaction equipmentand/or wet concrete where this exceeds the loads applied by earth backfillpressure and traffic surcharge during use (PD 6694-1 7.3.3)

15.1.9 Any special action not covered above - none

15.2 Heavy or high load route requirements and arrangements being made to preserve theroute, including any provision for future heavier loads or future widening - none

15.3 Headroom provided – 6.477m to crown of arch. The structure gauge used is that ofthe Ffestiniog Railway, North Wales, due to commonality in the dimensions of rollingstock, which will be exchanged between the two railways. This has previously beenaccepted by ORR (formerly HMRI) thus setting a precedent. A greater headroom thanthe minimum will be sought where it can be provided with reasonable economy toimprove the draughting efficiency of steam locomotives and reduce the risk of blowback.

15.4 Authorities to be consulted and any special conditions required

16 Devon County Council Highway Authority

17 Environment Agency

18 Wessex Water Company and other utility companies

18.1 Standards and documents listed in the Technical Approval Schedule – see Appendix A

18.2 Proposed departures relating to departures from standards given in 4.5 - none

18.3 Proposed departures relating to methods for dealing with aspects not covered bystandards in 4.5 - none

19 STRUCTURAL ANALYSIS

19.1 Methods of analysis proposed for superstructure, substructure and foundations –plane frame analysis based upon a one-metre wide strip to establish thrust lines andfoundation reactions. The existing arch will be assessed by the MEXE method tocheck for its capacity and to ascertain whether any strengthening is required to attain40t vehicle loading.

19.2 Description and diagram of idealised structure to be used for analysis – see AppendixB for general arrangement drawing. The idealised diagram will follow.

19.3 Assumptions intended for calculation of structural element stiffness – Young’smodulus for concrete 31e6kN/m2 short term and half that value for long term effects

19.4 Proposed range of soil parameters to be used in the design of earth retainingelements – K values applied as per Tables B.1 to B.6 in PD 6694

20 GEOTECHNICAL CONDITIONS

20.1 Acceptance of recommendations of the Geotechnical Design Report to be used in thedesign and reasons for any proposed changes – a ground investigation is awaited.For the preliminary design, conservative parameters based on Tables B.1 to B.6 willbe used.

20.2 Summary of design for highway structure in the Geotechnical Design Report – to be

confirmed. Anecdotal evidence suggests a rock cutting with steep sides. This will beconfirmed upon excavation and the stability will be assessed at that time. In theunlikely event that reinstatement of the former side slopes is found to beunsatisfactory, then measures will be introduced such as retaining walls, groundanchors or battering back the slope to a reduced angle within the railway’s boundaryor limits of deviation permitted.

20.3 Differential settlement to be allowed for in the design of the structure – nominally10mm. Differential settlement is expected to be minimal as hard rock foundationsprevail. Resin anchor tie bars and/or masonry keys are envisaged to ensure astructure that integrity of the connection is maintained. Masonry cladding will havelime added to the mortar which traditionally has been found to offer flexibility.

20.4 If the Geotechnical Design Report is not yet available, state when the results areexpected and list the sources of information used to justify the preliminary choice offoundations – to be confirmed
