马里兰州的200亿美元紫色线路轨道系统计划从公私合作伙伴中撤出该项目的设计建设联盟，该联盟在与国家运输机构的长期纠纷中，负责监督该项目的公私合作伙伴关系。

紫色的线交通构造函数s (PLTP) , which includes Fluor Corp., Lane Construction Corp. and Traylor Bros. Inc, said in a May 1陈述that it has been “unable to obtain the time and cost relief to which it is entitled” from the Maryland Dept. of Transportation and the Maryland Transit Administration (MTA) to address a combination of factors that added more than a year and $500 million to the 16-mile, 21-station project across northern suburbs of Washington, D.C. that will link to existing rail lines.

该项目的最新修订时间表原定于2022年3月全面运作，要求在2023年中期完成两阶段的开放。

紫色的线交通构造函数s had last month sought an additional $188 million to cover revisions to a crash wall design required by CSX Transportation, and suggested that continuing construction while complying with COVID-19 health and safety requirements could lead to a force majeure claim.

P3团队所说的因素超出了其控制，包括多次耗时的第三方诉讼。反对者第三次也是最后一次尝试停止施工的裁决是在4月初发生的，当时美国法官拒绝了他们认为美国陆军工程兵团对项目疏edge材料排放水的许可的争论是不当的。

其他障碍延迟了通行权的收购和环境批准，以及在2017年8月开始建设后实施的设计和第三方协议的更改。

“Regretfully, [the consortium] simply cannot complete the project under these circumstances,” said Scott Risley, project director.

Within days of the Purple Line Transit Constructors announcement, Fitch Ratings cited the Purple Line’s “heightened completion risk” in downgrading ratings for two of the project’s primary financing instruments—including approximately $313 million worth of state-issued private activity bonds and the $875 million Transportation Infrastructure Finance and Innovation Act (TIFIA).

惠誉还对该工具分配了负面的手表，这表明在未来几个月内有可能进一步侵蚀该项目的信用评级。但是评级机构表示，一项和解协议成功解决了PLTC问题，设定了可实现的项目完成日期，并确保付款即将到来的债务服务义务“可能会解决”否定的手表指定。

The P3 team statement noted that an exit clause in its contract allows the consortium to withdraw if total delays reach 365 days and negotiations have been under way with the two state agencies to resolve these issues for nearly three years. The agencies have previously suggested that some of the consortium's schedule and cost problems were self-inflicted.

在5月4日的注释中Fluor表示，其总项目积压将减少约12亿美元，这一澄清延迟了其10K备案。

州长霍根（Hogan）和州运输领导人表示，他们仍然致力于该项目，并愿意继续与紫色线运输构造师进行谈判，以减轻成本影响。

该财团计划实施其工作地点的“有序”关闭，这一过程预计将需要60到90天。
