Editing Interstate 93 (section)

====Rapid bridge replacement project====
In August 2010, in [[Medford, Massachusetts|Medford]], a {{convert|25|x|7|ft|adj=on|m}} section of bridge deck on the northbound side partially collapsed due to age-related structural fatigue.<ref name="globe-moskowitz2">{{cite news |last = Moskowitz |first = Eric |title = Officials expect I-93 north lanes in Medford to be open for a.m. commute |url = http://www.boston.com/news/local/breaking_news/2010/08/pothole_forces.html |access-date = August 5, 2010 |newspaper = Boston Globe |date = August 4, 2010 }}</ref> The collapse forced the [[Massachusetts Department of Transportation]] (MassDOT) to evaluate the remaining bridges along the corridor, eventually deciding to replace several bridges along the highway in a plan called 93 Fast 14. MassDOT set in motion a plan to replace the superstructure and concrete decks on 14 overpass bridges along that section of the Interstate, using [[rapid bridge replacement]] methods. The $98.1-million (equivalent to ${{Formatprice|{{inflation|US-GDP|98100000|2010}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}) project replaced bridges originally built in 1957 with a set of prefabricated modular concrete bridges in a series of weekend roadway closures. Traffic was diverted into a series of crossover lanes during construction. The main part of the project took place each weekend from June through August 2011, with the exception of the [[Independence Day (United States)|July 4 holiday]] weekend. One or two bridges were replaced each weekend during the construction time frame. The project was part of the commonwealth's Accelerated Bridge Program.<ref>{{cite web |title = I-93 Medford Bridges: 93Fast14 Video |url = http://transportation.blog.state.ma.us/blog/2011/05/i-93-medford-bridges-93fast14-video.html |publisher = Massachusetts Department of Transportation |access-date = June 20, 2011 |date = May 5, 2011 |archive-date = June 18, 2011 |archive-url = https://web.archive.org/web/20110618042625/http://transportation.blog.state.ma.us/blog/2011/05/i-93-medford-bridges-93fast14-video.html |url-status = dead }}</ref><ref>{{cite web |title = MassDot Accelerated Bridge Program: About the program |url = http://93fast14.dot.state.ma.us/about.html |publisher = [[Massachusetts Department of Transportation]] |access-date = June 20, 2011 |url-status = dead |archive-url = https://web.archive.org/web/20110608201046/http://93fast14.dot.state.ma.us/about.html |archive-date = June 8, 2011 }}</ref>
