这是由Lola Domènech设计的西班牙巴塞罗纳Passeig de St Joan大道改建项目。该项目于1859年被提出，由JosepFontseré'sCiutadella在1872年开始修建，全部共50米宽，两边种有高大的树木，中轴是一座公共公园。原本该场地被分为3区：1和2，从凯旋门到MossenCintoVerdaguer广场，除了行车方式以外，都很相同，这个部分是对称的12.5米管的路面，车辆和中央自行车道共25米宽，沿途有不连续的花坛，极其分散。3区市3个7.5米宽的汽车车道，3米的人行道，没测设有中央行人长廊，双向自行车道位于一侧。
新的设计设置了基本目标：优先林荫大道的行人使用，转化为一个全新的城市绿化带，右侧一直延伸至Ciutadella公园。为了实现这个目标，该项目通过以下三个城市规划标准：
1. 沿着林荫大道，保证其延续性，
2. 城市空间要满足和适用于不同需求和用途。
3. 将Passeig de St Joan大道改造为新型的可持续的城市绿色区域，并予以推广。
这个新的提案获得了来自各界的好评，充分体现了称呼司空见的社会价值，也提供了多用途和功能的需求，解决了生物多样性和可持续发展。通过这条旧街区的改造，可以振兴当地商业和康乐生活。同时再次将其历史价值——林荫大道，展示在世人面前。

The layout of paseo de St Joan as an important 50m boulevard was first laid down by IldefonsCerdà in his Ensanche project, approved in 1859. Cerdà’s isotropic layout of 20m-wide streets also features various main 50m-boulevards with wide pavements lined with two rows of trees as well as a central roadway. Passeig de Sant Joan is one of these. JosepFontseré’sCiutadella project (winner of the 1872 contest) featured a new central promenade which was to prolong the Salón de St Joan. The Ciutadella fortress was demolished and turned into a public park and this led to the prolongation of paseo de St. Joan thus recovering the vertical axis featured in Fontseré’s project.
Although the 50m distance between façades remains constant along the entire stretch of paseo de St Joan, we can distinguish 3 different sections along the length of the boulevard:
Sections 1 and 2, from Arc de Triomf up to MossenCintoVerdaguer square are very similar and only vary in the way the traffic lanes are distributed. In both sections the layout is symmetrical with 12.5m pavements, a 25m roadway for vehicles and a central bicycle lane. On certain sections of the pavement there are discontinuous parterres which are in a very bad state and create a very fragmented impression. The state of the road paving and the pavements is very precarious causing problems of pedestrian and road accessibility. In section 3 the layout is completely different to the other two due to the transformation undertaken in the last urbanisation project. This section features a central 29m pedestrian promenade with three 7.5m car lanes and a 3m pavement on each side. The two-way bicycle lane is situated on the promenade on the llobregat side.
THE PURPOSE OF THE INTERVENTION
The new remodelling proposal sets two basic objectives: to give priority to the pedestrian use of the boulevard and turn it into a new urban green zone extending right up to Ciutadellapark.
DESCRIPTION OF THE INTERVENTION
In order to achieve these objectives the project has adopted three fundamental urban planning criteria:
to guarantee the continuity of the section along the length of the boulevard. Despite the fact that this part of the boulevard currently consists of 3 differentiated sections the remodelling intends to create a new longitudinal section making it uniform along its entire length. The new section is symmetrical and extends the width of the current pavements from 12.5m to 17m, maintaining the century old trees and accompanying them with two new rows of trees. The layout’s continuity is absolutely essential in order to ensure functional clarity along the entire length of the boulevard.
