Motorists who are among the 17,000 cars that travel along Route 7 in Branchville, just over the Wilton line, will be taking the scenic route this weekend \u2014 through the village of Ridgefield. Yes, all the traffic on Route 7 \u2014 figured at about 17,000 vehicles a day on a Saturday and 13,000 on a Sunday, according to the state Department of Transportation \u2014 will need to travel along Ridgefield\u2019s already congested Main Street. Those traveling north along Route 33 into that town will also likely be affected. \u201cSome people, when they look at me, wonder if I\u2019ve lost my hair,\u201d First Selectman Rudy Marconi said when asked about the plan. The closure of Route 7 will be a little north of its intersection with Route 102 in Branchville, and the detour will be via Routes 102 and Route 35. The highway closure and detour will last for 56 hours straight, starting Friday night at 8 p.m. and lasting until Monday morning, June 12, at 6 a.m. With the weekend hours, the detour won\u2019t take place when there\u2019s work going on at the state\u2019s bridge project on Route 35, by the Fox Hill condominiums \u2014 that\u2019s a weekday job. This weekend\u2019s highway closure is part of a $3.5-million bridge replacement job that is expected to create four additional weekend-long highway closures, with detours through Ridgefield, between now and fall \u2014 \u00a0probably two weekends in July, one in August, another in September. The job will replace an unobtrusive bridge where The Norwalk River crosses under Route 7, shortly north of the train station \u2014 just a stone\u2019s throw from The Little Pub. While Route 7 will actually be closed in Branchville at the southern end of the detour route where bridge work is being done, at the northern end of the detour \u2014 at the intersection of Route 7 and Route 35 \u2014 the situation will be managed by Ridgefield Police. That will allow local traffic to reach destinations along the two miles of Route 7 between the Route 35 intersection and the Route 102 intersection in Branchville. But those two miles will be closed to through traffic.Additional policeCapt. Jeff Kreitz of the Ridgefield Police said the department will have four additional officers on duty throughout the weekend \u2014 at the expense of the state and its contractor. Police cars will set up at both ends of the detour \u2014 the intersection of Routes 7 and 102, and the intersection of Routes 7 and 35 \u2014 with another patrol car looking after things in the area in between. And the fourth officer and police car will be stationed right where the bridge work is going on, just north of Route 102 in Branchville. \u201cThere\u2019s going to be signage up, and the detour\u2019s going to be set up. The electronic message boards are going to be set up, advising of the road work ahead, and the detour route,\u201d Kreitz said. \u201cThe state is setting that up.\u201d Although locals will doubtless have their short-cuts and long-cuts around what seems an inevitable traffic snarl, Kreitz said police will try to keep cars off of Ridgefield\u2019s smaller local roads. \u201cAny of that through traffic, we do not want to inundate those roads at all,\u201d he said. \u201cIs it going to be busier? Absolutely,\u201d Kreitz said. \u201cThat\u2019s just common sense.\u201d Fire Chief Jerry Myers said the firefighters who drive ambulances and fire trucks will be ready. \u201cObviously, We\u2019ll have a boatload of traffic running through town. But it\u2019s Ridgefield, so we\u2019re kind of used to a lot of traffic,\u201d he said.\u2018Functionally obsolete\u2019The bridge being replaced dates to 1928 according to John Dunham, district engineer for the state Department of Transportation. The decision to replace it was based on inspections which the state does every two years or so. \u201cThe overall superstructure was rated as poor based upon field inspection,\u201d Dunham said. \u201cAs a result of field inspection and engineering analysis the structure was determined to be functionally obsolete and hydraulically inadequate meaning it could not pass the 100-year flood \u00a0storm event.\u201d The state\u2019s estimates of the amount of traffic that\u2019ll be detoured through Ridgefield is based on traffic counts on Route 7 on a weekend in March 2014, which found 17,223 vehicles using the highway on Saturday, and 13,088 on Sunday. At the time, the state also counted cars on Main Street, at the intersection of Routes 35\/33 and 102, near Jesse Lee Church. The totals were 12,432 on the Saturday, and 10,281 on Sunday. Based on those numbers, the detour from Route 7 can be expected to more than double the usual Main Street traffic both Saturday and Sunday.Double whammyMarconi is frustrated that the town is caught between the traffic nightmares of the two state bridge projects and he envisions worrisome scenarios developing. \u201cA wide-load trailer coming down Route 7 is going to be detoured all the way up 102, take a right that\u2019s almost impossible to take with a tractor trailer, onto Main Street, come down through Main Street and quite possibly not make it through the temporary bridge [on Route 35] for two reasons \u2014 either too wide, or too heavy,\u201d he said. The expectation is to re-route trucks through Redding. Marconi is also concerned about the state of the detour signs, which were put up almost a year ago. The one near town hall has fallen over, with no one addressing it, \u201cwhich means no one\u2019s ridden the route and inspected all of the detour signs,\u201d he said.
