Every given day there's probably dozens of miles of lanes that are closed due to crashes or refurbishment. Probably a lot more than that depending on where you cast your net. Whats another stretch of road going to do on aggregate anyhow? When bridge work or sewer work goes on over these same roads they go down for years too, sometimes totally down with no travel at all, e.g. in LA it took the city 8 years to replace the 6th street viaduct in Downtown LA and traffic was forced to detour for nearly a decade. Yet the sky didn't fall, things carried on basically how they always have with hardly a noticeable impact, and now that the bridge is open today I wouldn't say that traffic in the nearby area has been dramatically changed one way or another. There was plenty of redundancy and spare capacity in the network as it were.
