“西雅图华盛顿大学校园的下雷尼尔维斯塔项目创建了一个新的视觉框架，引入了西北太平洋最壮观的景色之一。设计降低了道路的高度，在其上方建立了一座陆桥，使其凌驾在多模式的交通枢纽之上。通过对广阔的草坪进行改造和重新布局，该项目重新修复了校园与雷尼尔山之间的视觉联系，从而完成了奥姆斯特德兄弟在1909年提出的设想。”
– 2019年评审委员会

“The Lower Rainier Vista project on the campus of the University of Washington in Seattle creates the framework for one of the most spectacular views in the Pacific Northwest. The design lowered a road that disrupted the viewshed and created a land bridge over it that covers a multimodal transportation hub. By regrading, reconfiguring, and reimagining its vast lawns, this project has repaired the visual connection between the campus and Mount Rainier first conceived by the Olmsted Brothers in 1909.”

项目概述
PROJECT STATEMENT

华盛顿大学的下雷尼尔维斯塔项目（Lower Rainier Vista Project）扩展并完善了奥姆斯特德兄弟的历史愿景：在众多交通模式的交汇地带建立一条具有重要意义的校园轴线。设计方案延续了学院哥特风格，并利用维斯塔层次丰富的地貌来框选视野、整合现代基础设施并提供新的ADA连接。一座新建的陆桥同时服务于行人、骑行者、公交和汽车，在新修的赫斯基体育场轻轨车站、华盛顿大学医学中心站以及校园中心之间建立了多模式的交通连接。

The University of Washington’s Lower Rainier Vista Project extends and completes the Olmsted Brothers’ historic vision for a monumental campus axis within the intersection of many transportation modes. The design references Collegiate Gothic forms and uses fine-tuned grading of the Vista to frame views, integrate modern infrastructure, and provide new ADA connections. A new land bridge facilitates multimodal integration of pedestrians, cyclists, buses, and automobiles between the new light rail station at Husky Stadium, the University of Washington Medical Center, and the University campus heart.

▲场地演变：奥姆斯特德兄弟的原始规划并未涉及到轴线端点以外的区域。经过一个世纪的城市发展，该区域由于没有正式的校园入口而逐渐变得孤立。新轻轨铁路的修建为该区域的重新设计提供了契机。Site Evolution: The Olmsted Brothers’ original plan did not address the land beyond the end of the axis. After a century of urban growth, this area became isolated without a formal campus gateway. A new light rail station prompted a redesign.

项目说明
PROJECT NARRATIVE

西雅图华盛顿大学的雷尼尔维斯塔起初被设计为1904年阿拉斯加-育空-太平洋博览会的轴心场地。由于连接了既有校园的半圆形平面和雷尼尔山的美景，半英里长的雷尼尔维斯塔很快就成为了这座西海岸大学与壮丽自然景观之间的标志性的存在。

在之后近一个世纪的城市发展和基础建设过程中，雷尼尔维斯塔作为校园门户和休闲场所的地位日益受到挑战。维斯塔的南侧（或者说“下部”）修建了一个地下停车场，加上周围主干道的扩张，导致校园的边界成为了一个大部分空置的、被车辆占据的场所。

完善维斯塔的契机产生于修建区域新轻轨站的计划。下雷尼尔维斯塔项目的构想是将新的轻轨枢纽与巴士、自行车和步行路线通过历史轴线与校园连接起来。五个政府机构合作推动了该设计的实现，包括华盛顿大学、华盛顿州交通运输部、海湾运输公司（ Sound Transit）、金县地铁运输公司（King County Metro Transit）以及西雅图交通运输部。在为期五年的设计过程中，设计团队以“恢复维斯塔轴线”为不变的出发点，对多种类型的复杂空间与政策上的优先次序进行了系统性的编排，旨在重新建立维斯塔原有的宏伟景观和体验。如今的维斯塔已经成为同时服务于步行者、轻轨、巴士、骑行者和汽车的、结合了多种现代化设施的全新纽带。

设计团队充分利用项目的巨大规模重新创建了下雷尼尔维斯塔的轴线，使其成为景观中最显著的“物体”。该轴线借助一座陆桥延伸至主要的巴士路线上方，在校园的南部形成稳固的存在。同时，它还为到达轻轨站的骑行者和行人提供了交汇的地点（另一部分骑行者来自于西雅图的基础道路）。为了实现流畅的陆桥步行体验，原本将维斯塔一分为二的公路被降低了20英尺，车道的新侧面采用了以当地矿场碎石填充的石笼墙来传达“切割土地”的意味。桥梁主体呈现为简洁的沙漏形状，回溯了大学早期建筑的哥特复兴（Gothic Revival）历史，同时还能够为从狭窄中心下方经过的公共汽车提供畅行的空间。

沿维斯塔的地形缓缓倾斜的新草坪成为了通往大学的“前廊”：一个用于集会、休闲和举办活动的场所，通过路径和小型广场将维斯塔与周边环境连接起来。草坪和维斯塔的层级变化创造出一种错觉，使远处的喷泉看上去比实际距离近，并且谨慎地利用水平元素掩盖了蒙特雷克林荫道（Montlake Boulevard）上的交通，使雷尼尔山的关键景观得以显露。在史蒂文斯路（Stevens Way）和陆桥之间，场地的坡度巧妙地塑造了“半岛”和“碗状空间”，在创造了丰富体验的同时也鼓励了位于轴线上的各种活动。

本地植物的分布位置经过了仔细调整，以适应既有地下车库造成的荷载限制，同时将下雷尼尔维斯塔的景观融入到更广阔的校园乃至远处的雷尼尔山的自然环境当中。高大的古树在施工期间得到了小心保护，并构成了轴线的森林框架。新的树木也被种植以保证未来的生态延续。维斯塔的南端需要种植能够适应阳光直射的树木，新生的树冠将在未来变得更加繁茂。

设计通过一系列照明、装饰以及维护策略，谨慎地保留了维斯塔开放和整洁的空间体验。简洁的预制混凝土长椅相互对齐带来集会空间；环境光强度经过了经过专门计算，保证了夜晚不会出现过强的光照；灯光设计包括与后方树林形成呼应的高杆灯和隐藏的倾斜轨道光源，后者既能够照亮道路表面，又能将陆桥弯曲的轮廓勾勒出来。

下雷尼尔维斯塔为大学校园的历史谱写了新的篇章。该项目为在现代城市校园内整合重要建筑遗产、大型交通基础设施和人性化的体验提供了宝贵的案例。

PROJECT NARRATIVE

The Rainier Vista at the University of Washington in Seattle was originally designed as the spine of the 1904 Alaska-Yukon-Pacific Exposition fairgrounds. Linking the pre-existing campus oval plan to the inspiring view of Mount Rainier, the half-mile long Rainier Vista quickly became the iconic representation of this West Coast University’s connection to its dramatic natural setting.

Over the subsequent century of urban growth and infrastructural expansion, the Rainier Vista’s role as a campus gateway and a place for strolling and relaxation increasingly came under conflicting pressures. The construction of a parking garage beneath the Vista’s southern or “lower” extent, in conjunction with expansion of surrounding arterial roads, led to the eventual blurring of the campus edge into a largely vacant, vehicle-dominated place.

The opportunity to complete the Vista emerged alongside plans for a new regional light rail station. The Lower Rainier Vista project was conceived to connect the new light rail hub with enhanced bus, bike, and pedestrian routes to the campus through the historic axis. Five government agencies collaborated to realize the new Lower Rainier Vista design, including: the University of Washington, the Washington State Department of Transportation, Sound Transit, King County Metro Transit, and the Seattle Department of Transportation. Starting with a strong design vision for reclaiming the Vista’s axis, the design team used this primary element, over a five-year design process, to weave together the complex spatial and political priorities of the many stakeholders. The design vision was to re-establish the grandeur and experience of the original Vista. It has become a new nexus of multiple, contemporary infrastructural systems, serving people arriving by foot, light rail, bus, bicycle, and car.

The design team leveraged the monumental scale of the project to re-establish the Lower Rainier Vista’s axis as a legible “object” in the landscape. Extending over a major bus route via a land bridge, the axis anchors the southern extent of the campus. It also serves as a point of intersection between cyclists and pedestrians arriving from the light rail, as another group of cyclists is passing through on Seattle’s primary regional trail. To accomplish the seamless pedestrian experience of a land bridge, the elevation of the roadway bisecting the Vista’s axis was lowered by twenty feet. The new sides of the carved roadway were expressed as ‘cut earth’ through a language of gabion walls filled with local quarry spalls. The simple hourglass form of the bridge itself connects back to the Gothic Revival heritage of much of the University’s early architecture, while also allowing clearance for buses passing beneath the narrowed center.

The newly planted lawns along the gently sloping Vista function as ‘front porches’ to the University: places for gathering, relaxation, and events, while connecting paths and small plazas link the Vista to its surroundings. The grading of the lawn and Vista creates the illusion of a foreshortened distance from outside of campus looking toward the fountain, making the fountain appear closer than it really is. The grading also uses careful placement of horizons to obscure Montlake Boulevard traffic from key views of Mt. Rainier. Between Stevens Way and the land bridge, the grading subtly forms a promontory and a bowl to create a variety of experiences and to encourage different activities within the axis.

Native planting, carefully calibrated to work with the load restrictions posed by the existing below-grade parking garage, draws the Lower Rainier Vista into the broader campus character. It also extends to the natural connection presented by the view of Mount Rainier beyond. Heritage trees, significant in stature and carefully protected during construction, compose the axis’ forest frame. New trees were interplanted for future succession. The south end of the Vista required plants that will thrive in direct sunlight, but also flourish in the future as the canopy of new trees develops.

The design was careful to preserve the open, uncluttered experience of the Vista by utilizing lighting, furnishing, and maintenance solutions that supported this vision. Simple pre-cast concrete benches align to create gathering spaces. Ambient light levels were expertly calculated, so as to not over-light the space at night. The lighting design consists of discreet pole lights placed against the backdrop of the forest frame, and a hidden lean rail light source that both illuminates the walking surface and outlines the curving silhouette of the land bridge.

The new Lower Rainier Vista adds a meaningful chapter to the University’s campus legacy. The project offers valuable lessons in reconciling the competing interests of a major historical monument, large transportation infrastructure, and human-scaled experience within the modern urban campus.
