De­lays dur­ing A9 bridges work

Im­prove­ments will cost £690,000

Stirling Observer - - FRONT PAGE - Chris Marzella

Two bridges on the A9, near Dun­blane, are in line for a £690,000 im­prove­ment pro­ject – but the scheme will lead to de­lays for driv­ers.

Work will be car­ried out on the Auchin­lay Rail Bridge and Al­lan Wa­ter Bridge, which carry the A9 over the Stir­ling-to-Perth rail line and Al­lan Wa­ter.

Ex­pan­sion joints – which have been in place since the bridges’ con­struc­tion in 1990 – have de­te­ri­o­rated and will be re­placed.

BEAR Scot­land, who are car­ry­ing out the pro­ject, say it will last for seven weeks and done in to two phases, with the first due to get un­der­way later this month.

A spokesper­son said the re­place­ment of the joints was com­plex and large ma­chin­ery was re­quired to help re­move the old fit­tings across both car­riage­ways. The new joints will then be set in place us­ing con­crete to re­pair the bridge deck, with both bridges then wa­ter­proofed and resur­faced.

The A9 will re­main open through­out the du­ra­tion of the pro­ject, but a con­traflow sys­tem will be in op­er­a­tion dur­ing the re­pairs.

Phase One will be­gin on the north­bound car­riage­way with sin­gle lane traf­fic in each di­rec­tion trav­el­ling on the south­bound car­riage­way.

Phase Two will re­peat the process, with works on the south­bound car­riage­way and traf­fic be­ing switched to the north­bound car­riage­way.

First phase of the pro­ject is ex­pected to be­gin on Mon­day, Novem­ber 19, with traf­fic man­age­ment re­main­ing in place un­til Wednes­day, De­cem­ber 12.

The sec­ond phase of the pro­ject is ex­pected to be­gin on Mon­day, Jan­uary 14, and traf­fic man­age­ment will re­main in place un­til Mon­day, Feb­ru­ary 4.

BEAR Scot­land’s North East Rep­re­sen­ta­tive, Andy Thomp­son said: “Over the years the joints have de­te­ri­o­rated and no longer func­tion prop­erly, and this pro­ject will al­low us to re­place the joints which will en­sure the bridge con­tin­ues to op­er­ate safely for years to come.

“The pro­ject has been split into two phases to re­duce the over­all im­pact of the work on road users, with teams re­mov­ing all traf­fic man­age­ment from mid–De­cem­ber un­til af­ter the fes­tive pe­riod to keep dis­rup­tion to road users at a min­i­mum.

“We’ve planned these works to be car­ried out un­der a con­traflow sys­tem to keep ev­ery­one safe dur­ing the pro­ject, and although some mi­nor de­lays are an­tic­i­pated our teams will do all they can to carry out the work as quickly and safely as pos­si­ble. We ad­vise road users to abide by all traf­fic or speed re­stric­tions put in place dur­ing the work for their safety, and to use both lanes when queu­ing to help re­duce any con­ges­tion.

“We thank road users for their pa­tience dur­ing these es­sen­tial works and en­cour­age them to plan their jour­neys in ad­vance by check­ing the Traf­fic Scot­land web­site be­fore they travel and al­low­ing some ex­tra time to reach their des­ti­na­tion.”
