Review of Winter Service Plan for Roads 2019 – 2020 A full review of last season’s plan was undertaken. A review of the actual journey times taken as per GPS trackers vs calculated times were also completed. All engineering areas for the forthcoming season will have dedicated salting units (1x12.5m3 unit in the Edenderry Municipal District and 3x9m3 in other regions). The 3 Municipal Districts will be serviced from 2 depots – Birr servicing the Birr Municipal District (Birr North & Birr South) and Tullamore Servicing the Tullamore & Edenderry Municipal Districts. Brine manufacture and storage facilities are located at both depots alongside dedicated salt barns. The use of Brine ensures that all salt is now pre-wet and thus the volume of salt needed is significantly less than that of a dry salt operation (up to 30%). The salting routes have been selected to remove (in a typical pre-salt operation) the requirement for refilling midway through the salting operation and to ensure that all 4 routes are completed within 4 to 5 hrs. All routes salted in 2019-2020 will continue to be salted. Following agreement with Tipperary County Council some changes were made to the Birr North and Birr South Routes. Tipperary Co. Co. have agreed to treat the stretch of the R445 which is within County Offaly running south west towards Moneygall as indicated in purple on route map. Offaly Co. Co. will in turn treat the sections of the N62 and R491 which are within Co. Tipperary North West of Roscrea and the section of the R438 from the Offaly/Tipperary County boundary to its junction with the R489 all shown in green on the route map. This change will assist better route efficiencies for both counties. _________________________________________________________________________ 3 Offaly County Council Winter Service Plan 2020 – 2021 _________________________________________________________________________ The treatment of the R440 and R441 from Birr to Cadamstown County boundary via Kinnitty which was previously in the Birr North route map has now been included in the Birr South route map in an effort to harmonise the overall travel times of the 4 routes within the County. For 2019 – 2020 winter maintenance season, the R421 Killurin to Laois/Offaly County boundary was added to Tullamore salting route. Laois County Council agreed to salt from Coolagh Cross at R421/R422 junction to Laois/Offaly County boundary along the R421 as part of their northern route. In addition, in 2018 we received a number of requests from emergency services to salt the R490 from Cloughjordan to Moneygall. The R490 was identified as an important emergency corridor to the M7 during Storm Emma in 2018. Following discussions, Tipperary County Council have agreed to treat the R490 from Cloughjordan to Moneygall and Offaly County Council will treat the R489 from Rockview to Riverstown as it would be mutually beneficial to both local authorities. Traffic Counts Traffic counts were undertaken on all Regional Roads in the County in May 2012 and subsequently in May 2019 on selected routes of our network. Changes to the 2013 – 2014 Winter Maintenance Plan resulted. The 2019 – 2020 Winter Maintenance Plan included 2 no. additional routes from Killurin to Laois/Offaly County boundary in addition to R489 from Rockview to Riverstown as mentioned in review above. This Traffic Data has been subsequently used to prioritise the addition of new routes since then. Route Priorities The Tullamore to Edenderry route via the R402 had been included as a priority 1 route in 2018/2019 plan. The R420, Clara to M6 motorway had been included as a priority 1 route in 2018/2019 plan. _________________________________________________________________________ 4 Offaly County Council Winter Service Plan 2020 – 2021 _________________________________________________________________________ Priority zero routes have been included during extreme weather events following the experiences of Storm Emma in 2018. These are emergency corridors which must be kept open at all times and include: Shannonbridge Power Station on the L-90357-1 Edenderry Power Station on the R401 The responsibility for the M7 Motorway was changed to the NRA (Now the TII) in 2013, but it still retains Priority 1 status. Treatment Matrix The treatment matrix was previously modified as the bulk of Offaly’s operation incorporates prewet salt and thus a reduction in the salt requirement for prewet operations is now the norm incorporated in the matrix. Policy It is the intention of Offaly County Council to deliver a coordinated programme of winter service operations on routes of given designated priority. Routes are designated a priority rating of between 1 and 3 based upon the particular class of public road, traffic volumes carried and the importance of the route on a national, regional or local level. The priority rating assigned to a particular route also has an associated stated level of service to be delivered on the route. This Year in terms of traffic volumes the following rationale generally applies: - Priority 1 - All National Roads & Regional Roads >5000 AADT Priority 2 - All Roads 3000 - 5000 AADT Priority 3 - All Regional Roads >1100 - 3000 AADT _________________________________________________________________________ 5 Offaly County Council Winter Service Plan 2020 – 2021 _________________________________________________________________________ The table below details the Routes of Designated Priority for inclusion in winter service operations: - Route Description Level of Service Priority Those routes which are essential to be kept To be treated 1 serviceable in all weather conditions as far during all as reasonably practicable. weather events Tullamore Municipal District M6 Motorway section thru Offaly Section* N52 Tullamore – Kilbeggan N52 Tullamore By Pass – Blueball N80 Charleville Roundabout – Killeigh Co Bdy R420 (Old N80) Clara -Tullamore R420 Bachelors Walk – Cloncollig Roundabout – Ballina X R420 Clara to M6 motorway Birr Municipal District M7 Motorway section thru Offaly Section* N62/N52 Roscrea - Kennedys Cross *** N52 Birr-Riverstown N52 Kennedys Cross-Fivealley N52 Fivealley – Blueball N62 Ballinahown - Cloghan N62 Cloghan - Galross Cross N62 Galross Cross-Kennedys Cross R445 Roscrea – Borris in Ossory** Edenderry Municipal District R402 Edenderry - Enfield R402 Edenderry - Ballina Cross * These Sections of Motorway now form part of TII MMARC Contracts **A short Section of this Route Transverses Offaly and is treated by Laois Co.
