Eight bridge maintenance workers fell into the water and only two survived.\r\n\r\nThe bridge sits at a vulnerable pinch point\u2014spanning a narrow channel where large ships enter the Port of Baltimore, the ninth-busiest US port. In the days and weeks following the incident that forced a closure of the port, global supply chains and port revenue suffered.

Proximity to the US capital meant oversight by leaders of federal agencies and the White House. Additionally, being on the busy East Coast meant quick access to necessary equipment and personnel. Responding agencies each connected their enterprise geographic information system (GIS) to the others' to seamlessly share web maps, web services, 3D scenes, and other data.\r\n\r\nWithin just six days, a new channel was opened for shallow-draft vessels. By the 30-day mark, half the channel's width was cleared, allowing deep-draft vessels to pass. In 76 days, the original channel was fully restored.\r\n\r\n\u201cBy working together, we turned months into weeks\u2014and bounced back faster than many could have ever anticipated,\u201d Governor Wes Moore of Maryland said <a href=\"https:\/\/governor.maryland.gov\/news\/press\/pages\/Governor-Wes-Moore-Statement-on-Full-Re-Opening-of-the-Fort-McHenry-Channel.aspx\">in a statement<\/a>.\r\n<h3><strong>Supporting Individual Roles for Cross-Agency Collaboration<\/strong><\/h3>\r\nIn the first 24 hours of the bridge collision and collapse, first responders focused on a search and rescue mission. Then, the US Coast Guard, which oversees waterways and bridges that span navigation routes, took the lead. Its Marine Transportation System Recovery Unit started working to reopen the Port of Baltimore as quickly as possible.\r\n\r\n\u201cAt the start, we pulled together bridge blueprints from the 1970s. By the third day, we built a GIS dashboard to focus on creating new channels,\u201d said Lt. Commander Ian Hanna, lead of the Coast Guard\u2019s Response GIS Support Team. \u201cWe knew it was going to be a while for the main channel to reopen.\u201d\r\n\r\nThe Coast Guard set up a Unified Command Center at the Maryland Cruise Terminal. They added all key data to a real-time GIS dashboard, including vessel locations provided by <a href=\"https:\/\/spire.com\/maritime\/?utm_term=spire%20ais%20data&amp;utm_campaign=Maritime+-+Search+-+Phrase&amp;utm_source=adwords&amp;utm_medium=ppc&amp;hsa_acc=4934961383&amp;hsa_cam=20882694658&amp;hsa_grp=158416549873&amp;hsa_ad=685218173965&amp;hsa_src=g&amp;hsa_tgt=kwd-784030806924&amp;hsa_kw=spire%20ais%20data&amp;hsa_mt=b&amp;hsa_net=adwords&amp;hsa_ver=3&amp;gad_source=1&amp;gclid=Cj0KCQjw6oi4BhD1ARIsAL6pox1fhkwsvzqOV_aeYS0QGrbxUosojaasYwCXveK1qF1-3Zas7Ss-a7kaApoaEALw_wcB\">Esri partner Spire<\/a>.

Amilynn Adams, a marine transportation system specialist with the Coast Guard, built a site with <a href=\"https:\/\/www.esri.com\/en-us\/arcgis\/products\/arcgis-hub\/overview\">ArcGIS Hub<\/a>\u00a0to connect vital data and share the purpose-built apps from each agency.\r\n\r\n\u201cThe first 72 hours, everybody was sending me data over email,\u201d Hanna said. \u201cI was spending all night processing that and then posting it onto the dashboard. It was not sustainable.\u201d\r\n\r\n\u201cWe set up a call with the Army Corps, NOAA, and others on how we wanted to share data,\u201d Adams said. \u201cWe created a partnered collaboration group, with restricted access. We were all seasoned on data sharing details surrounding natural disasters and what that means in terms of data governance.\u201d\r\n\r\nWith portal-to-portal GIS connections, each agency maintained full control over their authoritative data. Shared GIS data layers included bathymetry, water levels, the temporary channels, and ultimately the cleared main channel. A 3D web scene visualized details of the salvage crews working to free the grounded ship and remove pieces of the bridge (see sidebar).\r\n\r\nAdministrators provided access to anyone who needed to see the data, from divers doing the salvage work to surveyors mapping the channel and White House officials monitoring the progress."},{"acf_fc_layout":"image","image":705322,"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"<h3><strong>Keeping the Map Updated<\/strong><\/h3>\r\nTo open the auxiliary channel, NOAA surveyed an area called Sollers Point at the north end of the bridge.

It brought everyone together very quickly.\u201d\r\n\r\nWith a constrained channel, a new level of traffic coordination was needed. \u201cWe built some tools to manage the schedule, using automatic identification system (AIS) data to highlight where vessels were coming in and out. It allowed the patrol commander to watch the scene,\u201d Hanna said.\r\n\r\nAn additional auxiliary channel, created in less than 30 days, was designed specifically for sugar barges from the Domino Sugar Refinery, a mainstay in the Port of Baltimore for more than 100 years.
